I think it's a mix of number 4 and number 3. I'll start talking with friends when they get into a new thing that I have already been in, and we discuss the more niche aspects of it. If a woman comes up, trying to discuss something I'm an expert in, then I'm going to immediately start talking about the more niche parts of it, as usual. Not my problem if she's either a liar or just isn't used to the rigorous questioning involved when men talk about things they like to other men.
