I'll take that as a 'Yes'.Love is an emotion comprised of affection, kinship, devotion, sexual desire, and admiration. There is no good reasoning to think homosexuals can't give each other that.
Did you know love (as opposed to your definition) is only rarely expressed through a sexual act. In almost every relationship every person has sex would not be an expression of love.
So .. let me ask you again. Do homos love each other?
