This tired justification of "child pornography", "terrorism" and "hate speech" has been beat to death to ban just about everything these days.
Why not ban cars ? After all both paedos and terrorists use them to carry out their evil, nefarious deeds. They both also use toothpaste.
I think is perfectly fine being un-able to shutdown sites for "social justice". If it ever escalates to being a major criminal problem, a legal case can be filed and it can go through the courts before the ban-hammer falls.
