You are correct in one point, Igy: Homosexuality is not "normal", quite literally because the norm is determined by the social majority. Heterosexual behaviour would appear to be the most common, therefore it is defined as "the norm". Neither normal nor abnormal are morally good/bad, however.
Secondly, you are categorically incorrect in saying that "you won't find a single homosexual" who notes and accepts this simple fact. There are in fact, many.
As for those that claim that their particular fetish is "normal", (these people are not restricted to the homosexual community as you implied) they are peddling nonsense, and should be ignored. We can accept that all people have different sexual preferences without conferring the frankly irrelevant title of "normal" to them and their preferences.
