The basic problem with that line of thinking is that most don't think immigration is such a large problem that we must have a zero-tolerance policy that does such harm. Immigration is a highly politicized issue that in reality has limited effects. Yes, it's more nuanced than "this is evil", but it's pretty inhumane and overly nationalistic / American-centered if you ask me.
> is that most don't think immigration is such a large problem that we must have a zero-tolerance policy that does such harm. According to who? I don't think that's true at all. I think immigration is the most important policy to get right.
Where is your judgment for importance coming from? What's your reasoning for making it such a huge priority? In a country with over 300M people, how is this relatively small amount of people having this vast of an effect? What is it affecting?
In terms of public opinion, consider this: https://news.gallup.com/poll/1675/most-important-problem.asp...
I wish there was a ranked system to see more than the single importance, but the point being that very few see it as a high priority issue.
I don't have specific data for this claim, but I think it's also safe to say the issue is a polarizing one: the group who sees it as the #1 issue thinks its a huge problem while many others see it as almost nothing. The disconnect there is exactly why I led with those questions above.
