Yep. If you start censoring them, then you are effectively doing the job of terrorists by trying to remove freedom.
Real life isn't Star Wars, the terrorists don't win if we "give into the dark side" to fight them. We just lose.
They don't win. They will never be... So, the west has become a police state, with lots of censorship, and they round up anyone who they suspect of disagreeing with their government and send them to re-education camps. That's it boys, we've won. Job done. Lets go home. Not going to happen.
Its important not to conflate "us losing" with "them winning". Because that leads to rhetoric like this... "if we do X, then the terrorists win"... which is nonsense. It's not a win for them. Its not what they are fighting about AT ALL. And it masks what they really ARE fighting about.
We shouldn't lose sight of that.
Censorship is bad, and should be fought for many many reasons, but "doing the job of terrorists" isn't one of them.
