That's like saying watch out for people who listen to m and m or Ozzy. There's nothing in any of that that makes you go homicidal. What abotu the hundreds of thousands of peopel who don't committ criems because of Al Gore's movie? How about watch out for people who're mentally unstable, better yet watch out for anyone you don't know. Maybe we shoudl watch out for you. You could be a crazy conservative who goes aroudn bombing abortion clinics.
