Why are they so obsessed with fighting "communists"...

It's absolutely necessary for a reactionary to see an "actionary" somewhere, real or not. Feeling persecuted is a fundamental part of their existence, and provides righteousness to what actually is maintenance of muh privileges.

Che and Castro were huge outliers. Fascism is the norm for the bourgeoisie in times of crisis.

If you count illusion based power built upon the uninformed, it is pretty high. Considering all the help from the msm for the narrative, it hasn't really done much though.

if power "doesn't do much" then it's not power, power is the capacity to do things.
