It is still a thing, however, not for hardcore leftists. They will be very fast in calling you a nazi or at least faschist if you utter sentences like that. I am guessing they dont want to see their utopia fail, so they ignore everything which would be evidence against their view of the world.

And its fucking sad, because I used to see myself as part of "them". However, this inability to reflect about ones own failings has totally alienated me.
