Counter-cultures aren't counter to whatever was mainstream 20-30 years ago, they're counter to whatever is mainstream today. Actual socialism is not and will never be well represented by corporate media, but is actually fairly common in the general population. On the other hand, those who are called (but do not call themselves) 'TERFs' seem like the perfect example of a counter-culture.
Must the movement be struggling to be considered? If it is just "what the majority political parties agree is unpalatable" then I guess we could say actual socialism or anti capitalism is there.
