Purely ignorant people are more likely to become victims, while arrogant people tend to have enough intelligence to knowingly absorb and regurgitate a particular dogma in a way that appeals to unsuspecting bystanders that were never given the tools to defend themselves. In other words, it's malicious "educators" that promote incendiary collectivism, usually by preying on those that lack the armor of reason. Ignorance is encouraged by these supposed teachers as a marinade; it tenderizes their victims and makes them ready to absorb more and more cultism.
Their arrogance is the key to all of this because these folks are really just middlemen for an agenda that is ultimately designed to harm them. They see themselves as brilliant minds that cannot be denied; they think they are the prophets of our age. They do what they do because they have a bias or hatred of independent thought, or, they believe they are earning a seat at the table of power by evangelizing for totalitarianism. The reality is that the globalist establishment will throw the leftists away as soon as they have what they want. History shows us that the most devout messengers of totalitarian regimes are usually lined up against a wall and shot once the revolution is achieved, but their hubris blinds them to this inevitable outcome.
They generally fall into two categories – the young acolytes and the aging adherents, and the vast majority of them are leftists. Whenever I examine the dangers of leftists I inevitably get accusations that I am "perpetuating the false left/right paradigm", but the people that make this argument don't understand what the left/right paradigm is.
