Your advice revels in the idea of angering enemies. Surely that is the very essence of toxicity itself? By pursuing something because you wish to annoy others?

I would suggest a better perspective is simply to forgive your enemies. That doesn’t mean you need to associate with them, in fact, you don’t even need to do it to their face, just show some compassion in your thoughts.

But don’t take pleasure in angering others, regardless of whether they’ve wronged you in the past, that’s just harbouring resentment.
