Why is Marxism so hateful and destructive, murderous and ruining?

Anytime a social fabric is uprooted by revolution old people, young people and women suffer. Marxists want to change the social fabric "by any means necessary. Those that traffic in revolution and demagoguery are people that invite tragedy on fellow human beings. These people are the WORST among us. Not only shouldn't we listen to them, we should shun them and stigmatize them for what they are, spiritually, intellectually and morally bankrupt.
