There can never be a substitute for open perception. As I grow, I see that I have never in my life felt the possibility of spontaneous goodness. Somewhere in a time I can’t remember, I adopted a mindset of “another day, another beating”. I adopted a mindset of endurance, and put aside any tender feelings, any possible optimism, any sensitive, open engagement with the world.
Yet this is precisely not just where happiness happens, but Goodness. I have defined Goodness as in part being able to be happy on your own. Logically, this means that if you cannot be happy on your own, your capacity for Goodness is greatly diminished, and the likelihood you will periodically turn to cloaked cruelty to salve your own pain greatly increased.
Islam is more or less the direct analogue in the moral realm of Leftism, in the sense that it is in a very great many cases openly cruel, violent, insensitive, inflexible, and rooted somewhere other than the present moment. It is a monstrous abstraction, in which cutting the arms off of children and decapitating women can somehow be made to seem good, just as it was made to seem good by Robespierre and Lenin and Hitler.
