We should remember the terrible things that happened on September 11th. We should remember those who died with honor.
However, we also have to look at the causes. I have said all along, though discreetly, that US foreign policy is to blame for much hate toward us. It is not that people hate our freedom. They hate how our freedom takes advantage of them.
Scott has a good post on some of these issues. One things he brings up is our dependence on oil. Just this morning on the way to work I saw a GMC Tahoe with a bumper sticker that read 'America Needs America's Oil'. We do because we drive inefficient boats like a Tahoe. That kind of stuff makes me furious. Many people here in Tulsa, connected to the oil industry, have a very vested interest in serving up as much gasoline as possible.
I also saw a bumper sticker that said 'God Bless America, To Hell With Our Enemies'. To quote JB Philips: Their God is too small.
