What if you were having a discussion with a person who was wrong like, 100%, you-know-for-a-fact wrong. You try to correct them. They refuse to listen to you/misconstrue what you are saying, so you tell them they are wrong again, but more forcefully this time. They become petulant and angry because they're not used to blunt talk or being told they're wrong. You stand by your point, albeit with some colorful, somewhat polarizing language, and tell them to feel free to continue the discussion when they actually have valuable viewpoints and facts to back them up. Or maybe you tell them the conversation's over until they're able to actually engage in a back-and-forth, reasoned argument with you, because right now they're just dodging your points and refusing to, essentially, acknowledge where they've been proven wrong and engage in a point-for-point, non-derailing, even-keel discussion. They get really pissed. But all you wanted to do was correct them because they were wrong - there was no hate in it. In fact, you were so emotionally detached from the conversation it kind of amuses you to see how upset they are.

Is anyone the asshole here? You just wanted to educate the dumb fucker. The dumb fucker, he took it personally, got his panties in a twist and started making ad hominem attacks. He didn't call you a goat-sucking cum-dumpster because he hates you, but because he doesn't know how to communicate, isn't used to being challenged, and is desperately trying to shore up his confidence in the face of someone who is quite determinedly and roundly kicking his ass to the curb on an intellectual/debate level. In fact, you might even sincerely feel you are doing the other person a favor by trying to educate them. Not only are you not trying to do harm but you are trying to HELP. And you're even willing to cut off the discussion after a while because you can tell it's going nowhere.

Both people walk away and at least one is seething and full of angry and hate (the dumb fucker, of course). But the smart guy was just trying to do him a favor! His intentions were good! Sometimes he wonders why he even tries with these people, but you know what, something in him just drives him to keep at it. One day, he hopes, one day someone will see the light.

Or at least admit when they are wrong and losing. Or at least be able to hold an actual debate instead of taking it personally. Practically, this smart guy is a hero, laboring for the betterment of all.

....uh....I know where I went here, but I don't know how to wrap it up beyond, like, so you're totally cool with all that right?

Or possibly, I feel like there are a lot of unstated caveats to your originally stated opinion and maybe it's just a little too generalized and broad. It kind of smells like "the road to hell is paved with good intentions." As long as you didn't intend to upset anyone, it's not your fault if you did.

I mean, like, when I slept with that married guy, I didn't mean to hurt his wife, but I did.

People's actions and words incite emotions in others. You say that a society where one group despises another isn't functional. Considering those two premises, how is it possible that one can say, well, whatever, as long as one's intentions are okay?
