Before WW2, Hitler would hold "rallies" and whip the people into a frenzy and they would go running thru the streets and any man would have his trousers pulled down. If he had the misfortune to be circumsized, it was considered to be "defacto" proof that he was a Jew and he was beaten. Often to death. Those people were Christians. Yeah, I know, they weren't YOUR kind of Christians.
Some of our homegrown zealots would have us do the same with any hapless person wearing a turbin. We've seen it in this very forum. Do we deport ALL the Godless, sub-human moozlims? What about those that have lived in this country for several generations? Get rid of them too, huh. What about the Godless, sub-human Buddist? And Shintos? They got to go, right? Then we come to any of those pesky Indians that have clung to their native beliefs. They were here first so where can we send them?
Of course, before we can start shipping any of these folks out, we've got to have a NATIONAL form of ID. State level won't cut it; can't trust those state-level people. Oh, that's right some gov'ment type --don't forget we're here to help you-- has already thought of that. But since some junior grade hacker with a puter and a printer could probably replicate a NATIONAL ID card in a couple of nano seconds, they'll probably need to go with computer chips imbedded in your head. Of course it's for your own good. No more walking around the airport barefooted. Just have some non-english speaking TSA agent scan your head and you're thru. Unless they're having a bad hair day and feel like jerking somebody around.
9/11 was a catastrophic event. The worst man-made event in most of modern American's memory and so everybody is looking under the bed at night for terrorist. They are screaming, "secure our borders". They are screaming, as they have been raised, for the gov'ment to look after them.
Sad truth is that the gov'ment can't possibly secure our borders nor can they prevent another 9/11. So you're pretty much on your own. Wow, you have to assume some responsibility for yourself. Of reassurance however, with 300 million people in the USA, the odds of there being a terrorist under your bed is pretty slim and if you see a swarthy complexed person wearing a bulky overcoat in July, avoid him and you'll probably be okay. Of course, don't walk the streets of our Nation's Capital after dark. To quote Marion Barry, two times mayor and convicted druggie, " 'cept for the killin's, this ain't no bad town."
For the DURATION of WW2, there were more American servicemen killed EACH DAY than died in 9/11.
