How would I know?
I have a relative that was killed by a drunk driver but that doesn't mean I get all sanctimonious with people who make jokes about drinking and driving. I assume they didn't know about my relative and so they weren't trying to offend so I give them a pass.
There are a lot of reminders of 9/11 out there. Everytime I see a passenger plane flying low overhead, I get a little nervous (isn't it a little low to be flying in this area? is it off-course?). But I'm not calling for air travel to be banned.
It is usually liberals who are always looking to find something to be offended by and thus trying to make everybody around them walk on eggshells.
I'm not a "walk on eggshells" kind of guy.
So I am a liberal now for pointing out the disturbing simalarities between the Visa commercial of a diver who dives off a muslim building and survives, while those who involuntarily "dived" off a tall building(WTC) due to terrorism.
I'm surprised you didn't call me hitler.
