I really don't think Homosexuality started or originated in America. I think that this has been a constant throughout worldwide history, it is a given, it's been here since the dawn of man and it isn't going anywhere anytime soon. America takes a different approach to these matters and the politicians and lobbyists fight hard within congress to make sure that regardless of whatever sexual identity, religious belief, code or creed you live by, you're treated equally as a citizen.
Sweden has taken the initiative to progressively move ahead leading the forefront for LBGQT equal rights. It seems more of a scientific and political matter more than a religious one these days (no offense to the religious), but to each his/her/it's own, I think the bigger picture may be finding equality among all the confusion.
Just my two cents.Q
