They're all calling him anti-semite, but the dude at one point was well known for his podcast with, his friend, the (at them time more e-famous) lazy-muffin/pillow/whatever. The dude has literal evidence of his friendship with a Jewish person, probably 1 more Jewish friend then those idiots have ever had.
Also, just based on the way max acts, I suspect he's maladjusted, and bad at socialising, even online, so going after him like this is like going after a person with downs for spurging out one time. Waters wet, fire hot, Max is awkward. Or you can just name and shame someone for the problems to get tumblr points over an argument about power puff girls (another tip-off that he might be unwell)
