I think many understand the consequences of highly restricted speech and how much benefit free speech has, including how censorship and tight control on speech has lead to undesirable government regimes historically. What people are really doing is reevaluating the costs side in the new environment where there's no longer a town square, information has the potential to spread to masses quickly, information is more difficult to separate from noise, and those with harmful intent can speak with more anonymity.

I'm a huge fan of free speech but the increasing potential damaging effects can't be completepy ignored. It's better if we can defend against such issues, in my opinion, and protect free speech, not ignore them and go on as is.
