No, scientifically the norm is the average. On average humans are heterosexual, but the range of sexuality is broader. Homosexual, bisexual, pansexual, asexual, paedophilia, philia of pubescant people (11-14/15). The last two are the only harmful ones, the last one dubiously (15 year olds can be very mature or very immature with even in early 20s people being vulnerable). This harm makes them in need of being criminalised.
Im discovering the word 'norm' is not a word I'm a fan off.
Recently there's been a feature about a Muslim gay guy, who is kind of living the two lives in one. He says he experience more islamophic critic than homophobes.
I'll try to link it in here later. (Mobile version) but also its in Danish.
