I've seen that argument (the one you're replying to) many times online and I never understand it. In the same breath people say that immigrants choosing to immigrate will have low wages and poor working conditions. Alright, but that's no secret, they know that and it's still better than where they came from, or they wouldn't move! Keeping them out hurts them or forces them into illegally immigrating.

The America First, America for Americans type people at least have a position that is coherent even if it's not compassionate.

The anti immigrant liberals for whom class solidarity ends at the border just don't make sense to me.

It's a purity thing. The left and right have their own notions of purity that have nothing to do with a deep understanding of morality. If these notions of purity are violated, they feel disgust. For the right, everyone knows what those notions of purity are (racial purity, bodily purity). For the left, hiring low wage workers is one of the triggering impurities, even if doing so leads to demonstrably utilitarian outcomes in the form of reduced suffering. So it's just people trying to avoid disgust triggers. Nothing to do with morality.
