I don't like him but... I've seen posters who support Trump so I'm not really surprised. that being said, according to the ideology of alt-righters like Fuentes.... the West should be purged of nonwhites (I think with the exception of AA's- I've seen one of the alt-right people say AAs should get a pass on staying) to make the West into a white ethnostate.
I think these people end up appealing to some Muslims because maybe they don't see Muslims critiquing liberalism slash cultural marxism (which some people call "wokeism" or "SJW" ideology and which its supporters call "being progressive") ... and so these people come on... Trump, Fuentes, Tucker Carlson, these people... they come, they relentless attack the SJWs (except Trump... Trump says anti SJW things but if you notice, he never really exposes their ideology in any depth... the guy rarely says anything insightful) and some Muslims find them appealing.
honestly I myself had sort of a quiet cooperation (quiet not out of being sneaky but quiet because I don't want to promote such types) with those kinds of people during the covid thing. I was with them on the anti-vax thing. but after the covid era ended with Russia invading Ukraine... I just don't find these people worth listening to.
Fuentes at least exposes the yahud, though. I've genuinely heard Fuentes say some interesting stuff. I have almost never heard Trump say anything insightful. People say things like "I just like Trump to trigger the libs LOL". Myself I don't find anything humorous or funny or appealing about some guy rallying whites to go out and hate crime immigrants and diaspora communities.
