My understanding of counterculture is that it 'counters'. I.e. it inherently searches to change or influence the dominant culture.

Your examples do show that we are (thankfully) not a monoculture. But they place themselves outside of our culture, instead trying to influence.

A good example of counter culture is BLM, Extinction Rebellion or Occupy Wallstreet.

Only thing: those are movements, not cultures. And they are, IMHO, generally ephemeral.
