These various 'isms' were never intended to 'work'. They were merely the excuse for slavery, impoverishment and mass slaughter. Those who do this regards human beings a little more than, and quite often less than beasts.
You may be right because death and destruction sure seems to be the outcome. Have you noticed how they cannot stand the light of truth? They will immediately stamp it out. For example, notice on the Sunday talking head shows (I don’t watch them much anymore)when the token conservative tells it like it truly is. At first the other panel members have stunned looks on their faces and then they launch vicious attacks, almost on cue, and do their best to drown out the voice. I’ve seen it so often until I can’t stomach watching these shows anymore. My blood pressure won’t take it.
