Anyone who believes ICE is legitimately trying to rectify illegal immigration is either too stupid to function or a liar.

Because I give the benefit of the doubt, I will assume most people are not that stupid. So, the only option left is they don't actually believe it, and it's just virtue signalling to their fascist overloads. Personally, I think that's a bit pathetic, not to mention naive. Nobody has any reason to think they will be spared, citizen or not.
