You're assuming you're getting downvoted due to the asexual aspect of your posts. I don't know whether this applies to other cases, but in this case I'm reasonably sure the reason is different: the existence and behavior of asexual people does not change how overall society works (sadly). In the very situation the BBC story refers to, it doesn't matter whether you're an asexual musician. The producer/executive/... would still expect sex from you. They don't give a shit, follow their ingrained patterns, and that's the problem. No part of "Everything is about sex. Except sex, which is about power." is in any way diminishing or erasing asexual people. If anything, it exemplifies the additional plight that being asexual brings, even over other LGBTQ+ preferences. Society expects you to be about sex & that's gonna be a very slow change.
