Armed goons terrorizing cities, dragging people out to brutalize and murder them is not "something very normal".

It's what the brown shirts did.

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.
