I’d agree that there is a difference between wearing a mask and throwing a brick and wearing a mask and making a political speech, but anonymous speech has a long and important history in this country, and it deserves to be protected.
Speech is one thing; anonymous brick-throwing is another.
Nobody has interefered with their speech, and in fact the anarchists get to spew their garbage through the mass media any time they want to.
Communists and anarchists can’t speak without a mask on because they’re criminals.
Anyway, criticizing them for being too cowardly to show their faces is not a violation of their right to free speech.
