This is really a great and rare article!
I wanted to share something from my experience. It might be slightly discriminating, I'm not sure, but I have a pretty good gaydar for recognising at least those males as gay that are weirdly a bit bitter or behave snobbish towards women at times. But such people can simply be misogynistic cis males too. Still the distinctive characteristics is most gay people also express pure longing for something that women are permitted to do, and not only look down upon women.
