Hacktivism & Hate
I can see both sides of this. On the one hand, the first amendment defenders and free-speechers are against this kind of action against hate groups online. And, it's not been effective over the long term. On the other hand, it is immediately and swiftly effecient in removing hate speech online in the short-term. And, it's completely effectual across national and international boundaries whereas the laws of individual countries have not been as effectual.
