I assume that whatever Progressives declare taboo and abominable must be very importantly valuable to their enemies. Aka, guys like me.
Take H8, for instance. The absolute moral consensus is now that "hate" is absolutely forbidden. If you are a "hater," then you are dismissed and condemned. No H8!
Cuckservatives often include disavowals of hatred in their attempts to defend their sinking ship, as in "I don't hate anyone, but..." Zzzzz. Accept your enemy's frame and you've lost. BTW, if you don't realize that they hate you, cucky, you need your brain transplanted. To remark as I have before, in all my years in San Francisco, I have never heard one passionate denunciation of Islam for its grossly violent attitude toward homosexuals, but venomous diatribes against Christians and Republicans are a dime a dozen.
In the New Faith of the Sons of Europa, however, precisely because our enemies forbid us to hate, hatred will be a virtue, a habit of soul and action to be cultivated.
As with all human emotions, it is pre-moral --in St Thomas's words, primo primi-- and certainly not inherently bad. One of Mother Nature's survival tools. It all depends on how you use it.
So part of the teaching of The Scribe will be to nourish hatred only
a. for what is a worthy object and
b. insofar as it serves your people and does not destroy you or them.
The sin here --the foolishness--would not be hating, but squandering or wasting it on what is not important enough to deserve it, as well as letting it rule you rather than serve you, so that, like every human passion out of control, it eats you up and becomes your master.
"Hate well and wisely," would be a moral maxim.
After all, in the Psalms does not God inspire King David in the beautiful Psalm 139 to sing, I hate them with a perfect hate? And if we are to seek after God-likeness, then that's a good model...
