here's a very simply concept for you.
by putting drunk driving statistics in the same sentence as 9/11 statistics and then saying the drunk driving statistics are WORSE, you are cleary saying that you think drunk driving is a WORSE crime than 9/11 was, or at the very least, you are trying to minimize and trivialize the worst terrorist attack in history. THAT is a simple concept to understand, except for you people apparently.
please try to put your heads around the mindset of someone who:
A) ties one on at the local bar to have some fun with some pals, drinks too much, and with impaired judgement tries to get into his car thinking he's ok and he can make it and everything will be fine in the morning, OR
B) conspires for years with 19 other people to systematically train for and carry out an attack that is DESIGNED to kill thousands and thousands of people as violently as possible
once you do that, please try to tell me as a human being that the person in scenario A) is equal to or even WORSE than the person in scenario B). or how can you even try to suggest that column A) belongs anywhere near column B) in any discussion about what is worse.
