I'll assume you're asking in good faith, so let me answer why I put my pronouns.

I'm mostly cis, mostly straight. I round up to a typical "straight white guy". I don't have to deal with the things trans people or gay people or women have to deal with.

But I am sympathetic to the fact that they lack a lot of the privilege that I have. So one way I try to show solidarity is by doing my part to normalize the idea that it's impossible to infer someone's gender from their appearance.

I list my pronouns to make it normal to list pronouns, because that makes life better for transgender people.

Does that make sense?
