Masses of people showing solidarity for Stone and Parker will not cause more terrorism.

Letting these fanatics know that their tactics of petty intimidation actually work will create more terrorism.

Agree. Caving to threats generates more threats. It's like when you've got a rabid dog snarling at you - you don't get it to go away by throwing meat at it.

Um, how do you get rid of a rabid dog? I don't see how this comparison is helping resolve the issue at all.

Unless it's poisoned.
