You're right. Human beings tend not to get along- it's in our nature to live in tribes or social hegemony, and compete. This is why globalization seems as if it wouldn't work. Human beings enjoy rallying under bastions of sorts. They need something to defend, to adhere to, to understand and to use to make sense of the world. Yours is "race", put poorly.
The problem is that people, by and large, don't worship sincerity. They will lie, and threaten, and "have some payback". They want to adhere to the concept of "us versus them", because it's the most common one- and the most effective one that easily captures minds early on. There's little thought required; you need only understand and feel, not question. It's not everyone, but try to find somebody who won't blame X or Y because Y or X.
Do you know how you break that cycle?
You exist as a contemporary individual in the modern age, capable of altering their behavior, and the behaviors of others. You establish "the greater enemy" for them to rally against- not force them to rally against themselves. That's old-school nonsense; it's never worked out completely.
Do you know what the greater enemy would be?
It would be the lesser entities that seek to divide people endlessly into disarray and chaos, because they simply can't get along or challenge their belief systems.
The enemy consists of the vices that strip us of our integrity, our acuity, our agency, and our current nature. Sometimes, it also happens that the enemy of your enemy is your friend- so it would be reasonable, but seem contrived, that you would still have to construct "a perfect lie" so people would stop becoming common denominators of nothing but screaming and flailing.

>flip like pancakes
>they let themselves be dominated
Dominated by what? Fear, or violence? They can't flip like pancakes and then subsequently come out, arms swinging.
I'm past the "muh race" meme/s.
