Its not an emotional issue, like the media makes it seem; its not really about the children. A country has a right to protect its borders and keep foreigners out. I think this focus on the children coming from South America in recent months is a moot issue- they've come over from there forever. Its the liberal media trying to to do what they always do, really: use emotion, as opposed to logic, to rally their base.
That said- I think these people are stupid for protesting the arrival of these illegals. If they really care about whats happening, they need to tackle their politicians and big business (or at least try, because we also know there are spiritual forces at work; I'm speaking in purely practical terms). Doing what they're doing is like trying to rationalize with a bullet once fired, why it shouldn't hit you; as opposed to the the person whose trying to blow your head off. I get that they're making the point; but the problem with most conservatives of this sort is that they're idiots. They need to realize the <<source>> of the problem, and fight 'that'; not the end product.
If you look at Europe right now, Greece is the perfect example, people are rallying together- albeit too late, like the protesters in the OP- to kick out the illegal foreigners in their country. Since the governments over there have done nothing, thanks to their engagement with the the EU, the people are coming together to tackle the problem on the ground on their own. Of course, the media labels them as neo-nαzι's and fascists. But that's really not the case at all. Still, as in the above example, I blame the Greeks for letting themselves be lured into the EU for the promise of quick profit and financial benefits or what ever, which we can now see has done more than backfire on them. They had to then agree to their 'rules' which included open borders. At the end of the day, its much worse for both them 'and' the foreigners who are in Greece (and other countries) now, all because the Greeks were fools. They should have taken this seriously BEFORE the financial crisis. Attacking the immigrants, and not those who employ them or those who allowed them to come in the first place is insane. We cannot be lured into a similar position.
Our economy is gonna come down crashing here pretty soon (look at our debt- it is inevitable). We need to tackle this by its horn and stop being so reactive and start being proactive.
