Funnily enough, I think MAGA is driving more people to Hasan who don't know him like you. And, I mean, he shares those same opinions so 🤷♂️
MAGA is just obsessed with him because he's involved with DSA and they're trying to create an enemy to direct vitriol towards. In this case, it's the DSA who have had several candidates coming from the left of the Democrats win elections (almost like what they're running on is popular or something lol.) Being decentralized, they're trying to name a figurehead so they can demonize the org as a whole through a recognizable figure. Hasan, being a popular streamer, is who they picked seemingly because he was fairly left and said some very provocative things, especially out of context. That's the attempt at least.
Honestly, capitalism has done a better job at promoting socialism than socialism ever has. And this is kind of case in point lol. People that seek out this crazy radical watch him and recognize his ideas aren't radical. He wants everyone to have healthcare, to have access to education, to have their tax dollars go towards making everyone's lives better and not to forever wars and/or billionaires.
This tactic works on those who are uninformed. Those who seek information, it backfires massively.
