In a way it is not free speech because they choose to be anonymous, so they are not actually expressing "themselves". Perhaps they should take their stupid masks off if they want their lame voices heard.
You are yourself, with or without mask.
In the US, when the KKK were made to remove their stupid pointy hats with face coverings at their gatherings, most of them stayed home after that. Like the cowards they are.
Just because you don't want to risk your entire career/social life and/or get arrested doesn't make you a coward.
I can't even make sense of that. What does freedom of speech have to do with identifying yourself? It sounds like something one of those violently outgoing middle-east dictators would come up with.
Well, something like this.
