Do 9/11 memorials further the terrorists' cause?

The whole point of terrorist acts is to draw attention to the desires of the terrorists. Every time we hold a memorial for 9/11 victims, we remind people of who committed these crimes and, indirectly, of what they were fighting for. We give heart to their followers around the world who know how powerful their acts can be.

Do you agree that 9/11 memorials further the terrorists’ cause? If so, is there any way we can honor the dead without helping out the terrorists, or is that a price that must be paid? If you do not agree, can you explain how this publicity does not help the terrorists?

Overall, what is the best balance to be struck between honoring the victims of the attack and glorifying the infamy of the attackers? This is not the only place where we see this happen. Think of John Wilkes Booth or Harvey Oswald or Adolph Hitler. Will these names ever be forgotten? Will the causes they acted for (insofar as they had causes) ever be forgotten?
