My security and safety is reason enough for me. You may not agree.
I do not agree.
Nor does Ben Franklin, among our other founding fathers.
Then there's the old saying, if you have nothing to die for, you have nothing to live for.
We (as a society, not necessarily individuals) trip over ourselves all the time thanking soldiers for their service "to protect our freedom." We, as a nation, have had guys lay their life on the line to (ostensibly) protect our freedom. Yet we have people in this own country who don't give a damn about that freedom, and would just give it up for, as Ben Franklin said, "a little, temporary safety."
Make no mistake, they will continue to find ways to claim that you are unsafe, and use that as a justification to further restrict freedom.
There is no such thing as 100% safety. It never existed, and it never will. There will always be the chance that something bad will happen. The chance is small, but nonzero. Even on airlines. The security that existed on 9/11/2001 is the same security that had existed for decades before that. The limited security on railroads is well-known. Plenty of things are possible. Things haven't happened, yet. Doesn't mean something never will (in fact, there have been cases of sabotage in the past).
Still, we're more likely to get killed crossing the street in front of our house than we are to be killed by an act of terrorism, even with pre-9/11 security.
Yet we have people who want to live in fear, and at the slightest hint that something might go wrong, they just surrender everything in hopes that someone else won't hurt them (and, to think, Americans like to make fun of the French for surrendering early during WWII; I'd hate to think if these folks had been in charge during the American revolution: "Sorry, Mr. British Soldier. I'll pay taxes to the king. Please don't shoot me! Here, have my house! Please don't shoot me!")
Why do people feel that it's okay to sacrifice everything worth living for in order to attain something that's impossible. What happens if you've given up every last bit of freedom you have, and they still say "well, you're not totally safe, so we need to do more"?
