They can. But it breaks against the trend.

Does it? The reporting on polls I've heard of sound like it has a few to many convenient assumptions baked in.

Answer that they is a limit to how much immigration is sustainable? Clearly you must think we're over that limit now.

Answer that cheating visa systems is bad? Clearly you must think the quotas are high enough as they are.

Answer that opening the floodgates would let in problematic people? Clearly you must think contrary to data! that the people currently being let in are bad (rather than that the process acts as a filter).

It's at least as complex of an issue as the new hot topic, where appropriately formulated polls can claim to find overwhelming support for either extreme position despite that (or because, really) most people seem to favor something somewhere in the middle.

Not at all. Opposition to immigration is rooted in practical matters, not “hate.” For example, loss of political control—both liberals and conservatives like immigrants who vote the way they do, and dislike immigrants who vote the opposite way: https://www.cato.org/survey-reports/e-pluribus-unum-findings..., specifically: https://www.cato.org/sites/cato.org/files/styles/pubs_2x/pub...

I’m a very obviously brown guy and happen to be an immigrant. Up until 2016 or so, most of my encounters with racism had been from homeless people. But in the last few years that’s quickly been overshadowed by white liberals getting angry that I don’t want to be part of their “rainbow coalition.” (And that has been over further overshadowed by well meaning white liberals acting really weird.) Despite living in a Trump precinct I have yet to encounter any racism from a Trump voter.
