It's really the smallest thing, like, if anything you could make the argument its too symbolic; but overall it's just helpful. Considering we have a lot of trans users, I imagine (as a c*s male) that having people, even online, refer to you by your proper pronouns could really make you feel good. We aren't a fucking Nazi website ffs, we have a lot of trans comrades and it's both helpful and (in my cis opinion) probably good to have a community that supports you (trans people) by mandating pronoun usage. It might seem small, but to the stupidpol types i ask you this - imagine you live in some Southern hellhole, and no one in your family or school uses your prefered pronouns. Now imagine you find a space like this - it's probably going to make you feel just a tiny bit better about yourself at least, even if it's just strangers online - at least it's something, y'know?
Love to all my trans comrades
Yeah, in a similar vein, I usually refer to it as being "impolite" a lot of the time when I'm talking about these topics with people who aren't exactly in the know about these things. It's both true and I don't think it carries as much of a moralizing/scolding tone when I really want someone to shut the fuck up without getting into a whole lecture about it.
