How is it political to talk about yourself in vague terms when introducing yourself to a group!? Would it be political if he said his hair is brown? How about if he mentions the color of his skin, is that political?

You make the statement political when you try to ban certain people from talking about who they are, if only white people talk about the color of their skin it’s not political to say you’re black, it’s political to try to block people from saying it. Saying you’re queer is on the same level of mentioning you have a wife/husband, in fact it’s even more vague, it’s in the same level of saying “since I was a boy/girl”, because queer does not necessarily mean non-heterosexual it can also mean non-cisgender so it’s an umbrella term to mean member of the LGBTQ+ community, if being queer is political then being heterosexual or cisgender also has to be, and I doubt people would be okay with having to step on eggshells not to mention anything that could make someone deduce their sexuality or gender. Hell, the same people who claim Queer is political are the ones who have the most problem with gender neutral language.
