I think they were allowed to expose themselves quite effectively the other day. Neo-nazis also found ways to expose themselves well before the invention of the internet. They still have their free speech, but they are not entitled to aid in expressing it from private entities. You can't "defeat" neo-nazis on a message board any more than you can "defeat" a racist grandparent at the dinner table.

Judging by the reaction to the recent events in Charlottesville, including the revocation of the daily stormer's registration, it looks like mainstream society is soundly rejecting evil.
