I agree, but that's unrelated to this point. Let's not waste time with "no u"s
Right, but he didn't object to the patterns of the larger electorate, so you're not disproving anything he said -- he specifically objected to "young minorities/the current social justice movements in America" and he's right. Polls showed the gap disappeared with young minorities and I think there's a big overlap with social justice movements and Bernie supporters -- that's where the anti-establishment angle really helps. GAF's image of Bernie supporters largely came from the /r/s4p spam they'd constantly post over here. Just look at this thread.
edit: and I'll back up my "
GAF is really fringe when it comes to the levels of Bernie hate." claim beyond those limited demographics since you mocked it.
After Hillary had won California and was the presumptive nominee, when GAF was in full rage mode because he hadn't dropped out, most dems were cool with him staying in. That included all races, all age groups, and all education levels. Most dems didn't vote for him, but most dems didn't have this crazy hate that GAF had.
