It's right up there with calling Lincoln a racist and vandalizing monuments to him. In other words, irrational.
Yes, they are devoid of morality. It might be said they've devised their own morality in which whatever they say or want at the moment defines "right" and "good." The definition is constantly changing, because it's not based on anything that is absolute or bigger than themselves. They are their own god. There is no absolute, infinite, personal God in their uneducated and unenlightened lives.
Great post M&M!! Unchecked, morbidly narcissistic egotism (worship of the ego) is a common (yea, ubiquitous) feature of Satanism. Megalomaniacal self-adoration never has and never will have any place in Christianity or any other moral ethos with a healthy view of Humanity.
CS Lewis invested a considerable amount of literary effort into exploring the extremes of egostism especially in regard to quasi-religious movements (like Satanism and Marxism). His famous Screwtape Letters, along with the Space Trilogy (Out of the Silent Planet, Perelandra, That Hideous Strength). There is likely no better treatment of the arrogant, blasphemous stupidity of far leftist anti-theists than is presented in these books.
Conservatives and other normal people often seek to identify flawed, amoral behavior in order to check and (if possible) correct it. Leftists on the other hand, seek to identify chracterologically-flawed, amoral people simply for the purpose of recruiting them into the leftist, anti-conservative cause (exploiting them).
Conservative:(addressing leftist) If we all discourage racial/sectarian hatred, we will make the world a better place!!
Leftist:(snorting derisively) WHAT!?! Make the world a better place !?! Why the f*** would I want to do THAT !?!
In a nutshell, the far leftists fully intend to convert the entire world to Marxist revolutionary socialism or destroy it trying. In that regard, the Cyclopian, obsessive fanaticism of the far left mirrors (or exceeds in some ways) that of the muzz.
One of the reasons I refer to far leftists as psychotic is that many demonstrate a complete and utter indifference to human loss and suffering. Indifference toward the suffering of innocent people is a symptom of a latent psychotic process in which the principle regards other human beings not as potential friends/allies, but as they would inanimate objects to be manipulated, used and if "necessary" even destroyed.
So the far left supports BLM, who murder LEOs, attack innocent white people minding their own business and other horribly destructive organizations, justifying it all in their own psychotic ideas of reference as "worth it" because they believe it furthers the cause of leftism.
