When I was at university I met the 'queers'. The biggest bunch of tools I had ever come across in my life. They were against gay marriage because it was a 'heteronormative' institution, they believed being gay was akin to a phase a social construction created by Germans in 1870's. Unless you were 'queer' into S&M, anarchy, veganism, and dating or identifying as a pan sexual transexual, you had no value. To these people gay men were the worst thing to be fall 'queerness' and the LGBT had more letters in it than the alphabet. And: if you DIDN'T bareback you were 'zero-positive phobic' as a matter of fact to talk about safe sex, made you 'aero-positive phobic' 
I didn't get laid at all during my time in university unless I was working at the bathhouse. Not that I found these 'queers' all that attractive anyway. They were all pseudo-punks who lived in the most chic and expensive neighbourhoods subsisting on a diet of quinoa and lentils who'd go on to graduate in hipster obnoxiousness and were sickly and waify looking. 
But yeah there's a whole culture of people that have taken post-modernism to the most fucked up dogmatic extremes that common sense goes out the window. 
Personally, I don't see how my wanting to not wanting to get sick is discrimination. I don't want to her diabetes, cancer or even the common flu. While I understand that there's discrimination against people with HIV/AIDS, I don't want to lead a life dependent on medication, nevermind not being able to afford said medication, cuz even in Canada not all medication is covered. 
I understand mistakes happen. The heat of the moment. Sometimes you're with a guy, the condoms are in your bag in the other room. He just tongued your ass reall good, you've sucked his precuming cock... You're making out, thinking about the condoms in the other room, his slick cock rubbing against your wet asshole. On some days you'll reluctantly slip his finger out of your ass and walk with a raging hard on to the other room. Unzip your backpack, walk back to the room, your semi-hard cock soaking your thighs in precum as you march back to the room where you'll lose the cognitive means to open the fucking wrapper and try to get back to that hot place you were at only some minutes. But if you do, and you slap that condom on, better yet, slip it onto his cock with your mouth, you'll feel damn pleAsed with yourself after your cum's all over your stomach or the sheets from the amazing deep fucking he just gave you, and his cum is inside a protective barrier where you both know you had amazing sex and feel even better that you were responsible about it. 
In the off chance that you didn't go to the other room to grab the condom becUse the tip of his cock was already opening your asshole, and his tongue warped around yours just felt too fucking good to stop now, because damnit we're men and when it comes to sex sometimes we act against our better judgment, like masturbating in a public washroom stall though it's against the law, you ride. He spunks in your asshole and yeah, it feels good. If he's kinky enough he'll ask you to turn around and squirt it back out, and you'll think it's hot to finger your ass with his cum till your cum. Then you'll mos his cum with yours, froth it Round your asshole and beg him to shove his semi-hArd cock back in. There. You're both one. 
Then you'll both be asking. Demanding each other for reassurances that you're both negative. All of the sudden that hot. Charged moment has become agonizing for both parties and you both are suspect, and angry with the other ready to cry foul on a decision that was made by both of you. You hope to god your next test will be negative. You hope to a higher being you renounced years ago. 
I think there's also something to be said for those who died agonizing, horrid, tortured ways because they in fact didn't even know it existed or what it was. I can dig making a mistake in the heat of the moment. But being responsible for the consequences. But I also think to actively chase it, plan it out, pursue it and then pass it on, is prick, selfish behaviour.
As for the rational that well I might get it one day, so I might as well get it over with, that's the stupidest thing I've ever heard. I also might drown one day. I may be hot by a bus too. Hell, these days a bomb may go off while I'm on the metro. Which to choose from? Should I just put rocks in my pocket and jump into the St. Lawrence, or walk into incoming traffic, or seek our ISIL and tell them I'm a fag that lives to get porked in the ass?
