I think you can’t stop feelings from arising.

ok sure but like an addict ought not to act on their impulse, similar to hate or the continuum of negativity. Like we can have an impulse or emotion, but we oughtn’t entertain it (if we categorically disagree with the ends it brings). To recognize that negativity, especially intense negativity, is a pathway to hate, and hate is categorically undesirable. It’s just like how urge to use drugs leads to a pathway that is categorically undesirable (i.e., addiction).
