Breitbart is hated because it has no support and audience out of it's very, very specific level of right wingness and authoritarianism. People further right see Milo and pals as a bunch of faggoty degenerates, people in the centre think he is a weird person with horrid and obnoxious manner/tastes whilst people on the left think he's an evil nazi. Nobody likes him except for a very narrow area of political thought.
