The Illegal Immigration Issue

Why is this an issue at all?
Basically, I believe that anyone here illegally is a "squatter," and those people need to return to the country from which they came. If not willfully, then forcibly.
There are ways to enter this country legally, but until they do that, they are willfully breaking the law by their very presence. Send them back, case closed.
It's about everyone having the same opportunity to come here legally. Why should we allow those people who take advantage of proximity and hike across the desert to stay here?
And don't call me racist for saying that. This issue isn't about racism at all. But while that subject is brought up, might I remind you that "La Raza" is about "the race." Their words, not mine. So who is racist?
