Rather than bash you here (even though, you should probably BE bashed here), I'll give you a couple of documented/witnessed facts of life to keep in mind:
1) Sept. 11 wasnt a movie on tv. It actually DID take place, -not by any domestic agents/govt. entities, or shadow-governments.
2) Nearly 3000 of our citizens were, in fact, killed that day by Islamic terrorists. Not by falling t.v.s, or furniture -(and not that any appliance or furniture apparattus has ever conspired to, trained to, and/or carried-out physical attacks on humans-except in Road-Runner cartoons) It's not about the #s of people killed before, or since, it's about HOW and by WHOM they were killed. I can assure you, had one of your loved-ones been amongst those killed in those attacks, your attitude would likely be very very different.
3) Those terrorists who carried out those attacks, lived and worked amongst us-via legal and less-than-legal infiltration. For every one of those who actually participated in the attacks themselves, upwards of 20-30 more folks assisted them- material, financial, logistical, recon, etc. We call them "cells". They were,have been and continue to be and operate amongst us, and they were, have and continue to strive to carry out attacks at some point in the future.
4)None of the 3000+ folks who got up, went to work, travel or whatever in their day-to-day lives that day, had any reason to think what happened to them would happen to them. Just like you today. YOU, however, dont get a choice in the matter.
If Jihad Bob decides to strap a vest to his chest and walk into where you happen to be today-game over. And Im pretty sure you wont mistake that attack as coming from a T.V. or a chair.
Now, does that mean all these TSA scans and all that crap make any sense? No. That's just Goverment being government, and seeing a oppty. to put more controls into effect, create some more agencies with which to have to fund with tax $$$, and a knee-jerk "HEY ! LOOK WE'RE DOING SOMETHING ABOUT IT, WITHOUT OFFENDING ANY PARTICULAR MURDERING SAVAGES, SPECIFICALLY" reaction.
Try not to buy or read too much into it, eh, sparky?
