The 7/7 bombings is what he meant it happened here in the UK.

Everything happened at some time, if we shit ourselves every time a prick with a death wish blows something up we'd be shaking in our safe little boxes never seeing the outside world, would you delay Christmas or valentines because a crapton of shootings and shit happened on those days? bungie day isn't something that just started yesterday, it existed before the bombings and it'll exist after bombings. If he wants the terrorists to win than he can feel free to shut himself in his room, close the blinds, and not partake in the bungie day, meanwhile the rest of us will be living on because that's what people that survive do, and before you call me insensitive, I'm a Bosnian, I was 6 when my country went through an ethnic cleansing, I was one of the handful of people that survived by sheer luck, so I know first hand what its like to have your people murdered, but here I am, alive, and not bitching every time something falls on a date I associate with a tragedy, people die, you live on.
