For what it's worth, I think your position is fair and the whole 'sealioning' people are strawmanning your argument.

I think your 'error' here was approaching a topic that is [post-facto] obviously sensitive in a normal (i.e.: less than sensitive) manner.

People get very polarized about politics[1] and your comments signaled you as being in opposition in some form wrt the "women's rights" position but did NOT virtue signal against their outgroup.

Consequently, your argument was interpreted as being pro-outgroup, hence the "you're a neckbeard"-style attacks.

Be more careful about sensitive topics next time.
