>Also, what if you disagree with me politically about illegal immigration - does that give you a "right" to ban me from your establishment?

If the owner said that in the US? Well, probably not. If this hypothetical establishment is open to the public, they aren't allowed to discriminate based on political beliefs AFAIK.

They could just kick you out for 'no reason', but that seems hard to do without pretext.

Someone's political beliefs are not a federally protected class[1] and therefore it is legal to ban them if you want.
