> Protests while wearing robes and masks however

This is absolutely permitted in America. It is illegal in countries like Germany which have no strong free speech protections.

No. It is not "absolutely permitted in America".

They're Klan Acts, because a bunch of guys in masks and robes marching through is obviously a threat of violence.

Those laws are frequently overturned as unconstitutional, but may still remain on the books because we don't do a good job of clearing out laws that were ruled unconstitutional.

As a general rule of thumb, almost every time someone brings an edge case about whether or not speech is First Amendment-privileged before SCOTUS, SCOTUS rules in favor of the speech. (The main exception is speech of students in school.) SCOTUS hasn't specifically ruled on anti-mask laws to my knowledge, but I strongly doubt it would uphold those laws.

The last court case was 2004, and the New York anti-mask was upheld.

You don’t have to pontificate. The link was right there.

Random aside, I haven’t seen NY enforce the anti mask legislation during the Halloween parade, various protests, or Covid. So I bet a new constitutional challenge could be erected.

You're trolling right?

There’s no issue protesting in masks. Antifa did it all the time with no repercussions.

There are places where it wouldn't be safe to protest without masks. In that case people effectively would be losing their freedom of speech if it isn't anonymous.

Protests while wearing robes and masks protect the protester from followup action, and it also protects their families.

If you assume a just government that doesnt demand revenge for every petty slight, you are living in a fantasy land.
