It has nothing to do with hate speech and everything to do with the fact that sargon(and kthers) are as effective and vulnerable as they are.

Say what you will about him, but sargon is brought up so much all over the political scene on youtube, and he makes such a great introduction into his secror of the onljne world that he almost is a gateway of sorts. Sure peterson and Rubin might be evwn more effective at this, but Sargon likely doesn't have nearly the reach or connections that they do, making him that much more vulnerable and ripe for striking.

Point is, they hate him and his platform because THEY WORK.

There's also the fact that he's dabbling in actual politics now which means he's going to piss lots of people off who do have connections., and that's really all it takes for this shit to happen.
