I just don't buy this argument. I don't know if you believe this for your self but moral relativism does not work in the real world.
The crimes that these British people were wanted for are crimes in both Britain and in the US. Its just that the crime was not committed in Britain, but in the US. Again, this is not a freedom of speech issue and Iits interesting that you are arguing in defense of theocracy - because its THEIR society.
We have to use logic, and it is illogical to arrest a person for allowing Muslim students to name a teddy bear "Mohammad" and then subsequently demand her execution.
Also, the point is that 1 and 2 failed to work. I doubt the US would "kidnap" citizens from our allies without at least asking the host country first. It doesn't make political sense.
I think it just comes down to this: If one believes that the US is an evil, corrupt country that takes pride on stomping on the little guy, nothing will change one's mind about it.
