I had an argument with a leftist years ago about that revisionist history movie about Nat Turner: "Birth Of A Nation".

Apparently a lot of people were so fucking triggered that when they saw a little black girl being lead around with a rope by a little white girl (I don't think that would have ever happened generally, it doesn't make any sense), they decided that it was okay to kill the little white girl. I pointed out that Nat Turner ordered the murder of both children and an infant in the plantation home that he originally attacked (a family he knew well), even against the apprehensions of his own insurrectionist forces. Turner himself basically admitted that it was an act of ethnic cleansing and terrorism to try and end slavery by capitalizing on white fear of a race war.

The leftist response was that it was okay to murder all the children and infants because they could potentially grow up to be slave owners. So, not even a desire for redemption: no 're-education', no family separation, not even a gulag, just summary execution of infants for pre-crime and guilt by association.

In their mind, the world is already fallen and evil. Humans are evil. Only through Leftism and Utopia can the world be made right. The children are already evil by being human, and will be raised to be evil, so it's simply not even worth the effort to expend in order to save them.
