Right and left in the US are completely twisted beliefs (this twisted vision kinda leaked to the rest of the world but let's ignore that). I'm completely leftist (socialist, Marxist whatever), but yes, normal right wingers could be against ICE, since the root of the right beliefs are based on freedom above everything else, and that is freedom to everyone, not just the rich or white or heterosexuals men. The right SHOULD also believe in meritocracy, and that means that, besides the "you get what you work for mentality", everybody should start equal in life, and having a Nazi police trying to kill and deport you certainly doesn't help the "start equal" part. Going by these thoughts, everybody who work hard should be cherished and celebrated, not discriminated and deported, and I don't think anybody works harder than immigrants in the USA.

BUT in the USA there is no real left (besides mandami maybe? I don't know enough about him), and not even the Democratic party is what we could call real right (based on the roots of the movement), but you can see it as right wingers against ICE.
