We don't even really have to round them up. When they get pulled over for speeding. Detain and deport. I also favor sort of a homestead style program where qualified individuals are sent back, but given a one time entry visa. Come in. Stay a year. Prove up with a job and no state assistance. Adjust status to permanent residence with civics classes. Turn them into patriots.
I don't like this Trump-DeSantis battle. It's turning a lot of people off. Now some are declaring they won't vote if the other wins the nomination. We need both Trump and DeSantis (no, I don't buy that he's a ds plant), and we need all of their supporters.
What you are referring to as "the West" are the leftists trying to take it over, not the real West. Don't be mislead. I don't think Putin is the one to lead the world to freedom, although we do have an enemy in common in the Globalists. It is us that will lead the world to freedom.
You understand the conundrum though? I bought a house. I didn't pay for that house. Someone else did. Then I agreed to pay them back with interest for the use of their money. If things occur as you say, do I then get a free house? As nice as that would be, you know we can't sustain society if such expensive things are just handed out.
Try "misgendering" a trans and see if your free speech rights are respected. Oh, and trans people literally held a speaker hostage for a few hours because they didn't like what she had to say. She was one of the swimmers who lost to Lea Thomas.
