You still won't hear a coherent explanation but they always resort to racism. In every single conversation, save one, I've had with conservatives about this, they always fall back on "those countries are homogeneous". It's not even a dogwhistle at that point, it's just them being too cowardly to admit what they mean.

Of course, they can't logically explain why free healthcare requires an all white population. At best, they'll insist diversity makes us weak (they probably got that from tucker carlson, whose peddling his ethno state bullshit on fox now) because different cultures are different and that's bad.

But they'll ignore the fact that the majority of immigrants assimilate into "American Culture", and do so happily.
