Marxism and the Marxist umbrella of religions, e.g. Global Warming, Climate Change, socialism, etc.., have surpassed Catholicism by far in influence and have taken the overall top slot in social rot. The Marxist denominations have had profoundly negative impacts on every country. Christianity has had its low points but overall it has been constructive and positive. Hinduism and Judaism have been closer to nothing-burgers, ... you know, there but not much going on. Buddhism has been a substantial force for peace throughout history; you never read about any Buddhist jihads converting people at the edge of a sword.
The worlds major problems began when Karl Marx began to rave and preach. Today, children who fall sway to Marxism have little hope of being scientifically literate or mathematically competent ... and have zero hope of grasping economics.
Yep, Marxism is poison alright.
