I match what you describe in your ETA. I'm independent, but registered Democrat for the 2020 primary. I'm not committed to either party. However I won't jump to the "red" side of the ledger until or unless Republicans come to their senses regarding Trump and other issues unrelated to this thread.
I've lurked in this thread for quite a while. Sometimes saying "good point" or "I hadn't thought of that". Sometimes my head has exploded from what I just read and the eponymous cat and I have to hide under the bed for a while.
I'm a white cis-woman. Like Emily's Cat, I to not present as a very stereotypical woman (engineering, piloting a plane, skydiving, riding motorcycles, computer programming, hate to shop, think 2 or 3 pairs of shoes and handbags are plenty, and don't wear makeup). I was happily married to a man until his death a few years ago. Yet nobody, including me, has any problem identifying me as a woman.
Transgender and transsexual are different terms (I didn't know that), but both covered by the umbrella of trans rights. I don't think that people posting here have any problem with transsexual people with the exception of some sports, in which having a male body gives them an advantage.
Posters have tried to explain why transgender people feel like they are the opposite sex from the body they were born with and feel more like the other sex. That has been a hard thing for most other people to understand. However, those feeling can't be the entire story, as references here to a pregnant transman (aren't pregnancy, birth, and lactation the most female things that someone can do?) and transwomen who rape (something that is engaged in nearly exclusively by men).
So, the answer to that seems to be "well, they feel more identity with the other gender" - they feel like the stereotype of the other gender rather than the sex that they are. Seriously, stereotypes?
I honestly don't get what people who don't have a diagnosed psychological disorder mean when they self-identify. If someone can post or refer to an understandable explanation, I'd like to see it.
Most of the time, treating transpeople as they want to be treated works just fine. A transman magician, OK. A transwoman receptionist, fine.
The most contention seems to be over transwomen and what rights they have related to cis-women.
While women have been historically restricted in what they are allowed to do, in the U.S., that is mostly gone (at least legally). There are now laws helping women to catch up. Counting transwomen as women dilutes the intent and effect of those laws.
Comparisons with past injustices against POC and gays are not valid. The gay rights movement didn't decree that straight people must have sex with gay people. Yet the trans movement is making a big deal out of lesbians not being interested in transwomen. Women of color are not any different from white women, except for the color of their skin.
But (not sure how to write this - men who self id as women, but do nothing besides possibly changing their driver's license) are very different from ciswomen.
Men are taller, weigh more, and are stronger, than women. And are more prone to violence. That's true, regardless of what they declare themselves to be. Women don't want to be in vulnerable positions, such as a common changing area, with such people. Most men are not monsters or rapists, but the ones who are don't come with labels for women to identify them by. Women avoid situations where they are put in possible danger.
The trans activists here either completely ignore this aspect of women's lives or downplay the importance. Cis-men seem to understand.
Most sports favor the male body type. The fastest person on earth is a man. The best golfer is a man. The reason women's sports has become a thing, is that women can compete against other women like them, and not against men. Taking testosterone-reducing drugs does very little to erase the male advantage.
And finally, does the trans movement mangle other languages as badly as it does English?
I do not read or post as often as the frequent contributors, so a conversation may move faster than I can keep up with. I'll try to answer any questions or comments made directly to me. As a proxy, Emily's Cat often says what I intend to post.
Sorry this post has gotten so long. I just wanted to explain my position as a generally liberal but not aware of the full trans situation voter.
