>Do you equate freedom of speech with "abuse, harassment, and harm"?
Almost anything in CURRENT_YEAR can be interpreted as "abuse, harassment, and harm" by someone. Is saying "fuck Christianity and fuck White men" abusive, harassing, or harmful? What if Christians and White men interpret that as harmful? Will they take that down?
>Were these activities you wanted to perform in order to sign up?
Again, something as benign as "men cannot get pregnant" was a non-issue fifteen years ago. Now, that makes you a transphobic neo-Nazi.
That would probably more likely get you a polite correction on that type of forum. Partly because it's kind of a niche argument but mostly because it only invalidates the beliefs of the women who want to be men, who are often sidelined by their own ideological movement in favor of the men who want to be women.
By contrast, if you wanted to express some other truths that pertain to the latter group, such as "'trans women' are not actually women, they are men who desire to be women" or "there are a significant number of 'trans women' who 'identify' as women because they are men with a sissy porn fetish", then all their fury will be unleashed upon you. Even if you back it up with evidence and solid argument.
