In your comment, you said that we can just block the n-word. Why? Should it not also be up to the users offended by it to block those using it? I don't think people using the word should be on the platform, but I don't know where you'd draw the line.

> So you can't just create a rule that blocks everyone who says "He" just like you can block the n-word.

I don't think I've ever seen a single person suggest this.

> The problem is with the person assuming every single person in the general public should treat them as a friend and getting offended when a label that is applied to half of the population (neither as a positive or negative, merely as a descriptor) is somehow that bad of a thing.

I'm not sure what situation you're presenting here. Trans persons usually don't assume that the general public should treat them as a friend. What they assume is that "if I tell somebody I would like to be referred to with female pronouns they should do so" is a very normal thing to ask of somebody. I'm male, but if somebody erroneously called me female, I'd correct them. If they kept calling me female, I'd try to get them removed from the social situation I'm in. Why is this any different for a trans person?

> (neither as a positive or negative, merely as a descriptor)

This is a pretty bad line of argumentation. For racist people, the n-word is also just a descriptor, and they don't understand why they're not allowed to use it.

In the end, referring to somebody in a way they don't like is always a demonstration of power. By doing so, you're saying "it is okay for me to make you feel less welcome, because I won't suffer negative consequences from doing so". The only harm in making people feel accepted is an imaginary one.
