So what? Some people are goths, vegetarians, socialists, animal-rights activists, Scientologists, Antifa members, anti-vaxxers, Conservatives, etc, etc, etc.
You define yourself according to your belief.
Gender identity itself may be in a different category, much more personal and complicated - but the ideology around trans activism is just a belief. Some transsexuals are perfectly happy to say they are not actually female, but have adopted a womanly role. I've seen stories online where trans people get increasingly frustrated by trying to chase an unattainable goal of "becoming" the opposite sex, and feeling great relief when they come to terms with the idea that it's not actually possible.
Be proud of the "trans" part, is my own opinion.
But every time you use "cis" you are saying you have a gender identity that matches with your sex.
I will not be coerced into re-defining myself, the Oxford English dictionary, biological facts, and laws, simply to validate others. Don't force me to believe that males can be females, or that sex doesn't matter.
I tried, I can't do it.
If you are going to keep engaging on this thread, I am going to need some kind of sign that you are against the violence against women being threatened by some trans activists right now. Otherwise you are condoning the idea that people like me should be assaulted, raped or harassed.
It is this silencing and toxic atmosphere that prompted me to post this thread in the first place. Because I think it's dangerous, a 60-year old grandmother has already been beaten up for wanting to attend a talk, women have been doxxed en-masse, and it's bad for everyone. Stonewall or other LGBT organizations could help calm this down, just by trying to call for rational discussions.
You still haven't said anything about that?
Have a look at these threads documenting violence and coercion of women, lesbians -

If you cannot condemn this hatred of women, of lesbians, with the horrific dehumanizing language and open calls for violence, then I cannot continue to engage in any kind of good faith. Because it means you agree with them.
