Its all narrative, buzzwords and slogans with no real basis. I mean really just look at how they go on about saving the environment and reducing emissions, then started burning Tesla dealerships because owned by a "enemy".

They are so twisted that telling they see other correcting them as others being stupid and use that to feed their egos. Nothing good comes from talking with them.
