I've maintained for a while now that gay lib would also lead to straight lib. As society gets to accept that gay men are "normal" and that it's OK for gay men to love each other, straight men will feel more comfortable hugging, holding and even kissing each other. Not because they find each other sexy, but because it's no longer "evil" to love another man, and therefore things which might be interpreted as "loving" a male friend are no longer taboo. And actually, even if you do make love to him, so what?
So with that thought in mind, I share with you these pics of Colin Donnell and Stephen Amell from the series Arrow (which I haven't seen). They're both "straight". But they're not afraid to show their affection for each other. It reminds me of Heath Ledger and Jake Gyllenhaal, obviously also very fond of each other.
