Eh, all that is just people doing people things really. Echo chambering political opinions and talking about goofy internet shit is just the way college be in the modern world; the neckbeardiest thing you can do is to sit by and smugly pretend you're better than them. 

Like, in my experience the awkward nerds aren't the ones who just have nerd hobbies. Really, what twenty-something or teen-something dudes don't talk about video games with other dudes their age? The problem is when you get those people who don't get basic social etiquette and start monologueing about shit nobody cares about. That is annoying. I used to work with this one dude, for instance, that spent an hour or so listing off all the reasons the Stormcloaks had the most righteous cause in all of Skyrim, as if he was some sort of fucking Windhelm Bill O'Reilly. But if a bunch of kids want to get together and BS about Magicka or Minecraft or whatever, who really gives a shit, so long as they don't pummel other people who are not interested with that shit. 

...that being said, yeh, bronyism is the exception. That shit is [i]never[/i], under any circumstance, acceptable. Change your avis and sigs, burn your plushies, and lynch your waifu, and only then will you be free.
