Border security is not casual racism. Nobody takes seriously a notion to stop having borders in a nation literally defined by them. While many actions of the current system are reprehensible, the response is reform, or even a clean-sheet design. But loss of sovergnity is not on the table.
Thank you, and well said. It bothers me when I get called a racist and a xenophobe for saying that border security is necessary, but the current admin has taken it too far. It's not black and white! We can't let everyone in. That just doesn't work - some security is necessary. Turning people away for vague reasons or race/country of origin when they otherwise would be let in is a whole other can of worms though.
You might want to learn about the country specific caps and how bills like S.386 were passed in congress buy blocked by Sen. Durbin to keep the "casual racism" going.
This is also the reason why people from India enroll in colleges that have weekend classes in order to maintain their legal status while in-between jobs.
