People are pretty great on average, taking care of each other while trying to get by. Save your strength and spare the hate when ya can. Thats the post.
What is a must is combatting it. Hating something before you choose to combat it is optional, so long as the decision to combat it is made.
In other words, if someone hated something, but did not combat it, that would be ineffective. If someone combatted something, but did not hate it, that'd be fine.
The choice and the feeling are two completely independent things.
