Sure, words can have subjective meaning that can change from person to person and even over time. So two people perhaps don’t completely agree what it means to be a lesbian. But the general idea usually is something that can be agreed upon. But what is the point of arguing against monosexuality in the first place? Because to me it sure sounds a lot like the “you haven’t found the right man” argument. Even if I was attracted to men and was in some kind of denial, like you implied in your first post, it doesn’t change the fact that I don’t want to date men, simple as that.
Also I don’t think you argued concretely towards my historic argument? To me it makes it sound like you’re implying women willingly chose to be exclusively lesbians and men, exclusively gay, to fight for wlw and mlm rights. Which i can imagine some did, but certainly not everyone.
Are the axis you are referring to romantic, platonic, sexual, etc. attraction? Because I have no problem with those, but in that case I identify as a romantic and sexual lesbian.
And yes I would say denial is a very strong word. It implies you know better about how a person feels than themselves.
