Anti-mask laws - Wikipedia
I found out tonight
that in Germany it is illegal to protest with masks on because then people can commit violence anonymously.
In checking, it is illegal in many countries, including some U.S. states
This is revealing
"Many anti-mask laws date back to the mid-20th century when states & municipalities passed them to stop the violent activities of the Ku Klux Klan." Antifa is the doppleganger of the KKK, anonymous to intimidate.
