Christianity; the World's Most Violently Persecuted Religion

[The Architect Of Fate]

That a small percentage of humans behave in an unnatural behavior does not make it "natural" in any moral or practical sense; there would be many crimes that would be "normal" (happen often) that we still would not consider normal.

You have not demonstrated it's unnatural. It's most definitely natural. The question of morality is separate and no Homosexuality is just as moral heterosexuality as long as it's consensual and between unrelated adults. Nor is it impractical because this assumes that reproduction ought be the purpose of sex. No ones saying crimes are normal homosexuality is not criminal in an of itself.
