good but impractical advice
Hate is like a livewire. One wants to keep it from harming others, but one can't just grab it without insulation. One has to walk a fine line to know how to handle hate without subtly succumbing to it.
True enough .. but 'non-participation' is not the way. Where would we be if everyone thought that? I'm sure Winston Churchill would strongly disagree .. even if Neville Chamberlain wouldn't.
The 'subtle tightrope' you mention could well be, actively fighting evils and injustice, without as you say psychologically succumbing to hate. That's difficult but maybe possible in principle
