Send him a Christmas greeting card! No, I'm not telling you to do this because the ACLU would probably try to shut me down, but it is kind of funny in a way.
It makes you wonder if these cards are really from people who like the terrorists and they just don't know any better. Why on Earth would people send cards to terrorists is beyond me, unless it's to say something bad to them. Then again there are those crazy women who love men behind bars. I have no clue.
For the skin head terrorists we can send them Eid ul-Adha cards except they probably wouldn't have a clue what it was.
