Are people who are unable to understand concepts like love and commitment...?

Nope, but that's the implication by fundamentalists when they try to dehumanize gays.

Fortunately, gay people don't need Christians to validate whether or not their emotions are legitimate and real.

Edit: I don't think you understand satire. Have you ever seen the daily currant or the onion? You may not have noticed, but I employ satire quite a bit. Sorry you missed it. Fundamentalists say "gay love isn't love" because it helps dehumanize gay people in their minds. Like they are lesser humans, second-class citizens, because they don't understand love.

Love is accepting and embracing everything the person is, love in general is not just selfless, but also selfish. It is a symbiotic relationship, where another's happiness is their own.

Someone who loves another is not going to threaten their lover in order to get them to serve their desires, that is just called obsession, not love...

this is the type of question brought up by some 12 year old who's parents are getting a divorce

No person alive is "less than human".

You mean Christians? The ones who are brainwashed and follow in blind faith?
