In the US we call that the National Guard. The state governor controls them. In no way are they for this sort of situation though.
I don’t care what the dictionary says. I’m telling you what every American means when they say “militia”: crazy fringe conspiracy theorists who spend a lot of time discussing “the Jew problem”.
Your fundamental misunderstanding is that “militia” is a euphemism for “right wing domestic terrorist organization”. You won’t find them on Lemmy. There are a few small armed leftist organizations, but they wouldn’t call themselves militias and their mission is defending their communities. They understand that our government has always been tyrannical and a few guys with guns will just get themselves killed.
Don’t believe right wingers. (You can be forgiven for not knowing these were fringe right wing idiots. Media coverage tends to obscure that part.) They say they’re against government tyranny, but really they just hate brown people. (They meant the “tyranny” of having to sit at the same lunch counter as [slurs].) They love what is going on now.
Humming seems a bit odd. I wonder if those people are just humming to themselves.
I’ll do things like scuffing my feet, jingling my keys, or pretending to talk on my phone. I am a large guy and I naturally walk very quietly. I have scared quite a few women, and honestly, it is unpleasant for both of us.
