Will this stop or just encourage terrorists?

Blocking the content not only leads to a slippery slope — and open questions on choosing what content stays and what content goes — but also presumes that the block is the most effective way to stop the bad behavior associated with terrorists. But it leaves out that blocking such content often only makes those posting it feel like they’re on the right path, and that they’re saying something “so true” that it needs to be blocked. It’s not a path towards stopping terrorism or the spread of terrorist ideology — it just gets those engaged to dig in deeper on their views.
