I think there's a time to make a stand for ultimate truths, and a time to be a little more casual about it.
The prayer thing hits home for me. I did my first year of High School in a Catholic school, being a protestant (my whole town went to this school because our public sending district was shared with one of the state's most violent school systems). My attitude was ultimately 'when in Rome' and I didn't raise a stink over Hail Marys and the other Catholic jazz. I knew what I was, and 'playing ball' in that limited context didn't compromise my essence.
There are many claimants to ultimate truth but "the information's unavailable to the mortal man" (Paul Simon) so what we really have are a collection of mental models. Stories, basically, about what things mean and how things work. I think of them as different sometimes-overlapping collections of cognitive tools. In the modern world most of us have access to as many of those tools as we can learn to handle. But only after we learn to put them down, which is the hard part. Most people never learn to do that at all, maintaining a death grip on one story for their entire lives, and until we're ready to completely reinvent education from the ground up, we have to expect that.
Good for you for your accommodationist flexibility but do you understand that a Protestant from a different sect or region or era, one whose personal truth includes equating praying to Mary with sinful idolatry that would get you sent to hell, might have greater objections to being compelled to recite Hail Marys? No problem, if they can just change their beliefs, but...
So, to the topic, sure, there are all kinds of mental models, stories you can tell, that make it
perfectly okay that a female high school athlete loses a college scholarship to a male-bodied trans competitor.
- It was only genetic luck that gave the female athlete the ability to develop elite skills in the first place, so she has little reason to complain if arbitrary luck of a different type takes the opportunity away. An injury or illness could have had the same consequences and we'd call that unfortunate, but not unfair.
- It says "women's sports" on the tin and trans women are women if we make the definitions vague and abstract enough so it's just truth in advertising really.
- It makes little sense for colleges to be in the athletics business. In any sane world throwing a ball wouldn't be yada yada...
- Karma, man. She was probably entitled in her previous life so the Angels of Karma set her up for a lesson in expectations and disappointment, necessary for the progression of her soul, all for her own good, really.
- In the long run, we're all dead anyhow.
It's easy to explain or justify just about anything with just about any narrative, and all the more so if you're shifting between multiple narratives. But that's not what mental models or adeptness with multiple mental models are for. They're for making predictions to assist in making decisions. Scientific tools are good for predicting and deciding what arrangements of components will receive and process a radio signal. Skeptical tools are good for predicting and deciding whether an investment in Brilliant Light Power will return profits, or for predicting and deciding whether to rely on an imminent Second Coming to improve your life. Religious tools are good for predicting how individuals and societies will react to crises and propositions for social change. "Raw" narrative tools like myths, genres, styles, and tropes are good for crafting fiction (such as writing or role playing game mastering) and other related activities such as marketing.
There's a reason why adeptness with multiple models, "knowing many stories," is a rare ability. Because it puts pressure on another valuable quality: sanity. Take a look at a stranger on the train platform. In that moment, can you think of a scenario where it is absolutely imperative that you immediately kill that person? You can't? Okay, you're normal, if maybe a bit boring. You can? Great, you're a flexible thinker adept with narratives. But if you then actually go ahead and kill the person, or try to? You're a dangerous lunatic and need to be locked up. Because you're not the solipsist (even if you think you are), and your narratives coexist with and impinge on everyone else's.
The ultimate import of that is that society absolutely can make comparative judgments about accommodations of peoples preferences and needs. Here are some example hypothetical cases of someone requesting accommodation by a public school cafeteria.
1. "I'm a student who eats the school cafeteria meals daily. I don't like broccoli. I request that meal options that don't include broccoli should always be available."
2. ""I'm a student who eats the school cafeteria meals daily. I really like broccoli. I request that meal options that include broccoli should always be available."
3. "I'm a student who eats the school cafeteria meals daily. I have a documented extreme allergy to broccoli, such that even trace amounts transferred by utensils or surfaces can cause a life-threatening allergic reaction. For my safety, I request that no broccoli whatsoever be prepared or served by this cafeteria during my time here."
4. "I'm a student who eats the school cafeteria meals daily. I have a phobia of broccoli. Just seeing it on someone else's tray or even thinking about other people eating broccoli in the same room as me makes me very anxious and uncomfortable. For my well-being, I request that no broccoli whatsoever be prepared or served by this cafeteria during my time here."
Not everyone agree on which of these accommodations a given school administration should agree to, but we don't really have much difficulty coming to a democratic consensus on them in real life. We can see, for instance, that they're all different, so agreement with #1 or #3 doesn't automatically imply agreement with #2 or #4. We can agree that broccoli is not essential but that either banning it or requiring it would come at a cost to other students that has to be weighed against the cost of accommodation. We can agree that a verifiable physiological consequence is of more significance in the decision than subjective feelings of disappointment or discomfort, even if we're inclined to accommodate the latter anyhow. Lack of ultimate truth about broccoli is no impediment to making rational decisions about it.
