I'm certainly not gonna say your mileage can't vary, but I see over and over people on Tumblr etc making some commentary on why they like to identify themselves as queer, and getting younger folks replying to say "Don't you know queer is a slur and you shouldn't use it on people who aren't comfortable with being called a slur." And OP is left going "I literally.. was saying I like to use it.. on myself... Do you really feel the need to come in here and tell me my chosen self-identification is a slur?"
It's a new-ish phenomenon, seems to have started around 2014 when Tumblr got tired of policing fandom and decided to try policing identity politics.
I feel like I'm completely fairly dismissing the history and context of the people who hear it as a slur in the context of trying to police the word. For one thing, all words you can use as that kind of self-identifier have been used as slurs. For another, queer does indeed have a broadly shared positive context - from "We're here, we're queer, get used to it," to ubiquitous use in academics alongside the LGBT type acronyms. Not universal, no, but nothing is.
