Hatred is baaad, m'kay?
But there're so many things that drive me insane! Ignorant people, populism (yeah, politics is full of it), organized religion (monotheistic stuff, environmentalism), war on artificial enemies (terrorism&CP are popular nowadays, communists/imperialists before that), some GNOME developers (e.g. McCan't), orwellian corporations&governments, trolls that defend "intellectual property" (whatever it is, if it exists), socialist EU, BS like gender studies, Java and sooo much other stuff...
