Me, on the question of how sexual orientation is decided:
This comes down to the argument of “is it your attractions that decide your sexual orientation, or your behaviors?” And within the gay community, there is fierce argument over that question. Which is why I always go back to the Kinsey scale, which is based on attraction, rather than behavior, when defining my sexual orientation, because it’s a lot more clear what *I* mean when I say it.
Theoretically, it could be determined either way. From a practical standpoint, talking about a topic when different people have different definitions for the same terminology is problematic, to say the least, when real life issues are at stake.
