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
yes, yes it is. but 70-30 is very dude heavy but not quite enough to assume everyone you're talking to is a dude. the assumption has the consequence that women, femmes, and enbies, don't feel comfortable speaking up unless they're comfortable with people assuming they're men. even a lot of cis women aren't comfortable with that. remember when reddit used to whine that women would disclose their gender in posts "for attention"?
And then that reinforces it further. Non-dudes leave because they're sick of the environment and then it becomes more and more dude heavy.
