This is such a bullshit line of reasoning and it just gives these mandates their power. If you're trespassed because you're not wearing a mask then you get arrested for trespassing, you were arrested for not wearing a mask (in a given area).

In the state I live in, carrying a firearm somewhere that is posted "no firearms" is actually a trespassing offense by law. But you'd be retarded to say that you "weren't arrested for carrying a firearm."

It's a layer of obfuscation that prevents people from fighting it as easily.
