A bond of love between two members of the same sex. Controversy arises from superstition, religious cults, and ignorance surrounding the nature of nature.
It seems odd that so many claim it's a "choice." I'm guessing the right wingers also "chose" to be attracted to women and that they could snap their fingers and "choose" to be attracted to men as well. It's as though they think a teen will be in school one day and suddenly think... "How can I find a way to get beat up more?" You'll notice that bashing and hatred suddenly dies down when it's a member of your own family.
