I was in college (huge transphobe) and had a gender studies major sit me and some other students down for a 1.5 hour lesson
To my knowledge, queer can be used as a blanket term for “not-cis but it’s none of your fucking business.” At least this is how I use it anyway
Edit: The term might also help reduce violence against the lgbt. The current issue with cons and some libs is that they seem to think it’s alllllllllllll about talking about sex. A term like queer implies but doesn’t explicitly give details. Should they feel comfortable being fully out? 100%. Is that the safest move in the American christofascist-hellscape? Likely not yet :(
