I don't know where you're getting this “out of bounds” thing from. I didn't tell anybody to shut up. I didn't tell them that they can't say what they're saying. And even if I did, it's not like I'm in any position of power to force them not have that discussion. I just alluded to the negative consequences of having such a discussion (yes, discussions on the Internet do not exist in a vacuum, and they do have material effects in the real world, therefore we have a responsibility to choose carefully what discussions we have and what we say). People can still choose whether or not they want to have it.

Edit: I know there is no malice intended in this, and it's not directly related to the discussion at hand, but I would appreciate it if people didn't assume that my preferred pronoun set was he/him/his. In general, it's best to use they/them/their unless you've been explicitly asked to use otherwise.
