His logical fallacies don't stop just at ad hominem. Instead of providing a counter-argument to a valid point (sexual debauchery can lead to serious health problems both for men and for women, because our reproductive organs have evolved to be used in a single certain manner) he opted to lower himself to aforementioned name-calling, to appeal to authorities ("ancient Greeks did it" - as if everything that ancient Greeks did was good and moral), and to shift the focus of the opponent's point, put different words in his mouth and then proceed to attack him for something he didn't say - "it's not about sex, it's about love! And you cannot tell me whom to love!"
He's not just a gay, he's a colossal faggot!
