Yeah I've met those types too, I'm lucky to have a good BS detector though I think my gaydar suffered as a result lol.

I once used that to immediately call out one of my mother's old friends when I was younger, thing was, she agreed and was only because I took my mother to the side and calmly pointed out her friends bullshit harassing a store employee that she got out of that toxic relationship.

Always have either yourself or a trusted friend that can immediately call out bs.
