Here's what you, as well as Vixen, keep missing:
It's not that trans are sexual predators;
it's that sexual predators are claim trans.
Consider a parallel analogy. Consider an under age 10 child-only space, designed and intended for the safety and happiness of children. In previous years, the age in question has been based on the chronological measurement of age, from date of birth. Similarly, there are requirements for a person to have a minimum age in order to access certain services, such as driving, drinking, and signing contracts.
Recently, there's been an organized push for people to be accepting and supportive of people who identify as transage. These people have been discriminated against and treated as social pariahs, because most people think that identifying as a different age than one has chronologically is strange and deviant. There's been a lot of progress made in accepting that some people truly feel a different age than they are, and in many social situations their chronological age is irrelevant.
There's also been a push to change policy. The desired policy is to allow people, including children, to be treated as the age they identify as, in all scenarios.
If we were to allow transage people to engage in every aspect of society based on their identified-as age, AND we allow that age to be based on self-declaration in order to attain a transage identifier on their various documentation... what are some of the potential downsides and risks that might occur?
- What is the likelihood that a 16 year old might identify as 21, and thus be legally allowed to attain access to alcohol?
- What is the likelihood that a 40 year old with pedophilic leanings might identify as a 9 year old in order to attain legal access to child-only spaces?
- What is the likelihood that a 40 year old might seek to persuade a 12 year old that the 12 year old identifies as 21 in order to legally have sex with them?
In short: What sort of loopholes occur if we as a society were to accept a person's transage as being synonymous with their chronological age, and grant them access to spaces and services solely on the basis of their declared trans age? Are there potential downsides that may be exploited to the deficit of other people? Is there a potential for material harm to befall some people as a result of this policy?
How much harm to other people are you willing to accept in order to assuage the discomfort of those who genuinely identify as transage?
