Yes, the analogy to the bell curve doesn't fit this use case very well, I didn't noticed it before. But the point still stands: non heterosexual behaviour is a tiny minority compared to the norm. So, abnormal is a perfectly good word to describe non-heterosexual behaviour. Once again, it doesn't make it bad per se. I just can't stand word police, which is just another facet of thought police.

"Abnormal" has a very specific meaning. It is not used for everything that is just uncommon. It is used for behaviours that are non-normative. If you have an idiosyncratic way you use this word, ok, but communication is supposed to require and assume a common understanding of a language. So there is no point to discuss if abnormal refers to frequency of a behaviour in a population or in a normativity-related judgement of it, because in common usage it refers to the latter, because either we do not speak a common language or I have to assume disingenuity here (and leaning towards the latter in this case).

If the topic is about whether homosexuality is non-normative and heterosexuality is normative (with the actual, common meanings of the words), we can have a philosophical discussion on that.

Abnormal = non normal / non normative. Words have meaning. If for you it causes a bad reaction to it, you are the one that needs to deal with it. That's excatly the problem, normal people are tired of being called bad for seeing the world through normal, reasonable lenses. When a behavior does not follow the norm, it's abnormal.
