Yes this. Whenever I see someone self describe as queer I never assume it mean they are actually L, G, B or even T. Some are of course but most of the time, as you say, it's het coupled people who I assume find that fact about themselves too boring. It's such a reversal of LGB campaigning from a few decades ago where the goal was that your sexual orientation should be unremarkable and not say anything about you as a person. It's really not headed in the direction I thought it would. I often wonder where we would be now without the influence of internet and social media.
