The Linux world suffered from its own Eternal September, where every kid with some spare time has tried to install Linux and they're tribal about it. Of course Arch Linux requiring a little more time investment tends to attract that demographic of people with a lot of free time to learn, teenagers, that by definition are not fully matured emotionally. And some of those are insufferable.
I've been using Linux as a teenager since 2001, and it saddens me to read places where these congregate in mass, like /r/linux, and see the massively unfriendly and elitist attitude of some Linux users, berating others for using more user friendly distros or just because they're immature asshats.
One can write a whole book about how emotionally immature and insecure people become bullies when in front of a screen, but it's way off topic for this post.
