"Friendships are impossible with these guys."
I'm of the "mostly gay in a 4.75 Kinsey score sort of way" persuasion, and I have beenand still amgood friends with several straight guys. I have tried to fuck or "convert" zero of them. I fully intend to continue that trend. I have only had a crush on one of them, and I was not at all aggressive or lecherous about itpretty much the complete opposite, actually, because I didn't want to be awkward or strain our friendship. Hell, for exactly that reason, I didn't even tell him about my feelings until after they subsided, and I only did so because I felt that it was dishonest and creepy not to disclose something like that. It turns out he didn't even have a clue. That means I couldn't have even been subconsciously trying to seduce him or whatever other pseudo-psychological bullshit that people like you come up with to try to explain why gay and bi guys always try to get into the pants of any other guy with whom they come into contact, no matter how much they prove otherwise. Either way, my odds of finding a homophobe or a self-loathing closet case attractive or pursuing him are also zero, and my odds of even pursuing a friendship with one are pretty much the same, so don't flatter yourself. Frankly, I'm not that desperate, and you're not that lucky.
Similarly, I've also been friends with probably 25 or so other gay and bi guys over the years, and I still am friends with many of them. With only one exception, I have never fucked or dated them, and only a couple of them who weren't already partnered with each other before I met them wound up fucking or dating each other. Given my past experience and observation, that's roughly the general odds of any two individuals within a particular circle of friends hooking up regardless of gender or orientation, the bar and club scene notwithstanding, but that tends to be a vapid and degrading meat market regardless of gender or orientation.
"One guy was a neighbor and he kept trying to fuck me."
I strongly doubt that. Either you are delusional, flat-out lying, or he probably expressed interest in you once in a polite and tactful manner, then promptly stopped when you declined. Even if "he kept trying to fuck" you, then that simply means he is a creepy perv, not representative of gay and bi guys as a whole. No gender or orientation has a monopoly on creepers.
"I ended the friendship rather violently. The cops got called and everything. I took a baseball bat and put a fuckin hole in his front door!"
Assuming you actually did this, I like how you had to prove your masculinity by responding like a violent, unhinged maniac rather than simply doing what any mature, level-headed, and rational person would do: politely decline the offer, call the cops if they are unable to take no for an answer, and only resort to violence if necessary for self-defense.
"Well, that put a stop to that. Then I told people he was bi. He was furious! He was NOT bisexual!"
Again, assuming this actually happened, of course he was furious about it, you spiteful, inconsiderate jackass. You don't fucking out people. Do you have any idea how traumatic and potentially destructive that is? Or do you even care? The only case that outing people is acceptable is when all three of the following criteria are met: (1.) they abuse their power or wealth to promote the oppression and discrimination of LGBT people, (2.) you know for a fact that they have engaged in homosexual behavior, and (3.) you back your claim with evidence. Even then, the only purpose of outing an individual is to "disarm" them so to speak, not to hurt or avenge them.
"I see why guys do it though. Sex with guys is so easy. Easy as filling up your gas tank. Getting sex from women is such a hassle a lot of the time."
Sure, sex with guys is as "easy as filling up your gas tank" if you find guys who are that willing to put out, but it's just as easy to find gals who are that willing to put out too. People like that make me feel used and degraded, though, so I generally recommend avoiding sex with them.
