Permanent border control of any kind is on its face immoral. There is only one reason for this conflict—for some people wanting to arrive at a place and others wanting to keep them out en masse—and that reason is a desperate attempt by the haves to ensure that the others remain the have nots.
Anyone who claims to want to protect “the American way of life” or to want to keep other people from taking “American jobs” is saying—in so many words—that they want to keep the other party from enjoying the same standard of living that they do.
In short, the entire American nation is screaming at the top of its lungs just now: “WE WANT BROWN BABIES TO CONTINUE TO BE BORN INTO POVERTY AND TO DIE YOUNG, SO THAT WE CAN HAVE THEIR RESOURCES AND THUS A HIGHER STANDARD OF LIVING, DAMMIT!”
Legal/illegal? Ptah. It’s all a euphemism for domination and racism.
