If you're not for open borders and millions streaming in illegallly every year, you're literally a fascist. That's basically where the left is with immigration. There's no limit to immigration, and limit is fascism.

If the borders are often then no one is coming in illegally

there are quite a number of issues with the situation as it was evolved. lots of people are intersted as a matter of policy in admitting that the US is largely functional because of immigrant labor, but relying in illegal immigration to fill those roles hasn't been great for the structure of the country or the laborers themselves. and to be clear this is not just harvesting the crops, and raisin the children, and building the houses, its also doctors and engineers and all sort of other professions.

so there a huge need to have a difficult policy discussion about what to do without cratering the economy.

but when you start removing civil liberties and running around in gangs grabbing random brown people off the streets and sending them to indefinate detention in the middle of nowhere, dumping people in Somalia, claiming you have the right kill anyone you want, you shouldn't be surprised when people start waving around the f word.
