It would be solved if the only reason people opposed bank robbery was because it was illegal. But I've never heard anyone say "I'm only against illegal bank robbers, not legal bank robbers."
The antis who say "I'm only opposed to illegal immigrants, not legal immigrants", are either intentionally hiding their real reasons or simply aren't articulate enough to enunciate them, so in frustration they resort to screaming "What don't you understand about illegal."
But I've never heard anyone say "I'm only against illegal bank robbers, not legal bank robbers."
A better and more honest analogy would be: "Im only against bank robbers, not legal withdrawls."
Its that they didnt respect our laws enough to wait in line like legal immigrants. But I do have less of a problem with them than I do with our elected officials who undermine and refuse to enforce our laws instead of making a case for their support of open borders.
