Re: Getting rid of hate
I don't think that hate per se should necessarily be thought of as an embarrassing emotion to have. In some cases, hate plays a crucial role in stopping, say, a hateful person from dishing out further distress to you or your loved ones to the point of overkill.
Hate and anger will kick in, as quite appropriate responses, in many cases where, to give some examples, someone has unreasonably blocked your rise in the social ladder, you've suffered a slide in status, a friend has betrayed you, you've been threatened with violence, you've been subjected to malicious gossip, your partner has rejected you, a child you love dearly is killed by a madman etc. But it's crucial to distinguish clearly between those cases where a wrong has been unjustifiably committed against you vs. an action where it was, perhaps, justifiable. It's not always easy - shades of grey will doubtless exist in some instances. Moreover, different groups of people will argue differently about what's justifiable or not.
Still, it is quite possible, with a good measure of learning and strength, to ensure we let hatred run its natural course in cases only where a wrong against us has definitely been committed, rather than it spilling over into unreasonable anger at anything and everything. Rather than a world where hatred is eliminated altogether, the best scenario would be where everyone consistently tries to go out of their way to reduce unfounded applications of its reach.
