Like I said earlier, those who cover their faces are acting against the country's law or God's Law. And they are doing wrong.
You know, I've said the same thing myself. If you truly believe in your cause to the point where you are willing to die for it, you should be able to show your face. That goes for terrorists, criminals, or anyone else who tries to hide their identity while doing wrong.
And yeah, that goes for both the anti fascists as well as the white supremacists. If you believe in your cause, be proud of it and show the world who you are.
