@bear@queer.party The test I tend to use is take the statement im making and reverse the target to be whatever group im a part of. Then I ask myself if it sounds prejudice...
So for example I'm overweight. So if i hear the statement "Eww skinny people are ugly, I like people with curves".. I change it in my head to "ewww fat people are disgusting, I like skinny people". Well its obviously prejudice.
So for you I'd change it to "Gays [or whatever fits for you] are so annoying don't y'all get tired of being the bane of humanity". Obviously I think you could agree that would be a sexist statement, similar to how I perceived yours to be sexist.
