Yeah I can totally see that, I don't blame them. But what are the odds for you to go outside today and be struck down by lightning? Or to slip and fall, break your neck on a table etc.? Less likely to happen yet people have died stranger ways before. Don't get me wrong, I totally get what you're saying but death is the only thing certain in life and the moment we must leave this world eventually comes sooner or later. People will panic when something like the event in Paris happens, security levels will be hightened, new laws for more control get passed and then time goes by and everyone eventually forgets about it until the next catastrophe occurs. My point here is that hiding in fear sends the wrong signal. Again I'm in no position to judge, just trying to get a healthy discussion started 
Yeah. I was just making the point that if I hadn't been born here I'm not sure I'd have chosen to move into it- there's always someone worse off but it's not much of an argument that the people who aren't should make themselves worse off as a result (because making yourself artificially worse off will rarely make the lives of those who are worse off better, it'll just salve your conscience), or that the people who have a relatively decent life have no cause to complain about anything.

The other thing is, I don't really agree with your argument about other things being riskier. You're absolutely correct that some everyday things are pretty risky, but the difference is that those are risks that you can't avoid. Just because you can't avoid some risks doesn't mean that you shouldn't try to avoid other, possibly smaller, risks that you can avoid, if that's what you want to do.
Also what you're saying sounds awfully close to fatalism, which I don't agree with either.
Of course whether the approach you take to avoid those risks actually reduces the risk is another argument.
