A person is not illegal. Hence, the term undocumented. I think it is a pretty solid grammar. But that's beside the point. Now, I see young minds are being manipulated to support drastic immigration measure.
When I saw discrimination in America, particularly in the Bible Belt territory (I supposed many of them cannot tell Christianity and patriotism apart), I thought...perhaps the immigrants should try to impress the unprivileged Americans so much that soon, they will see those immigrants kinder to them than their own kins so much that they would do exactly what had just happened.
Nonetheless, though I favor the end, I do not feel it is heading the right direction. The methodology and cause is wrong. It's analogous to a sort of pity, which instills pride. Here, the liberals' extending equal rights to all humans would unfortunately triumph over the former ideology.
