I think it was similar with gay people a generation or so ago. Some straight people couldn’t look at a gay person without thinking about what they might get up to in the bedroom, or wherever. When I look at a person, I don’t immediately wonder what they do or don’t do in the bedroom & with whom.
I think this says a lot more about their personal insecurities about sex & gender than anything else, unless they’re just jumping on the bandwagon for political gain.
