This post makes no sense. It was not the ACLU or the left who tried to regulate porn. 

No liberals "go to bat for radical Islam" nor do they attempt to restrict the thoughts of those we disagree with. 

The racists/nazi/klan/alt-right and their supporters and enablers have every right to be free from government intervention preventing their hate speech. They do not, however have any protections from having their speech drowned out, derided, mocked, scorned, or countered in real time by all those who oppose their beliefs. If 100 white supremacist have a rally and 1000 counter protesters show up to drown out their hate, that does not violate the white supremacists 1st amendment protections to free speech. 

Challenging the views of those one disagrees with is not an attempt to restrict their thoughts.
