Unfortunately their cause has been usurped by political PACs and obnoxious activists who have completely lost the script.
Your cause isn't being helped by transgenders competing in female sports and unfairly dominating them due to their physical advantages.
I've spoken to older transgender people, and they are lovely and reasonable, and seem to only want to exist and get along without being bullied or shamed for their choices.
I totally support this ideal and believe people can refer to themselves how they wish, and do what they want, save hurting/harming others.
But I've noted there are activists who wish to usurp the natural order and demand everyone see things from their skewed and biased perspective...there is no gender and anyone who chooses to identify as male or female is "cis-gendered".
I don't appreciate being labeled that way. I am a man, a male and I expect people to refer to me that way, if you expect me to refer to you by your preferred pronouns.
