There are no "degrees" of hatred.
That's like saying there are no degrees of love or any other human passion.
And it leaves out the rather obvious point that one should hate evil and those who do evil.
Well, yes, there are...as to behaviors implemented. As to the motive, once hate exists, yes, it's a consistent banality, in that sense. Degrees are measured in how the hate is acted out, in my view. But the state of hatred, all badly capable of all bad, yes.
