Duped? I find that hard to believe. I mean, has no one seen some of the other movies he's been in? Machete in an ICE uniform... ICE has never been "good guys" and to be honest I already assumed he was a shithead just from that. This whole "good guys vs bad guys" crap was why Latino support for ICE and Trump had been so high leading into the 2024 election (also, Latino membership in ICE is fairly high). I think Trejo knew exactly what this movie was about. And if he's having second thoughts it's only because of how bad the optics have become for ICE, not that he doesn't still believe in it.
Alternatively, sure, let's say he was tricked. I mean, he's not getting hired for roles based on his acting skills so much as what he symbolizes, given his backstory. And I do think that's part of the problem here because it might cloud his judgement: he might think he's just playing himself for the umpteenth time, but I'm not sure he quite gets that for racists, his roles are confirmation of their stereotypes.
I can't sympathize with a man this rich lol. Good gods, I agree with everyone else here saying that he can't really be this helpless. I am sure I have heard about actors breaking contract, becoming un-directable, sabotaging productions, etc. He could push to get fired. Hell, if it's all as fishy as people claim, sue. Why care? Even if Shapiro has enough clout to ruin his chances of acting again (yeah, right), he's in his 80s. He can't retire already?
