LOL, I'm afraid of stupidity too.
This isn't about the holiday, this isn't about wearing the flags, this is really about the fact that Americans are getting jumpy when it comes to Mexicans in this country. Let's face it, just look at what's going on in Arizona.
Obviously, when you look at things in context, you see WHY these kids wear their American flags on this particular day, and you can also see why there would be tension on both sides.
They're a bunch of little kids and I'm not defending a side or saying the other is wrong, all I'm wanting to point out is that the TENSION exists and it's heavy right now.
If you're respectful of all races, then you take the context of today in consideration with what you say and how you say it, how you act etc., And that goes for both sides...
