Propaganda or personal experience or a little of both

 I don't know about propaganda in America. I grew up in a conservative suberb of  LA that was largely white when I was a kid. (It's changed over time and is more diverse). Yet I was convinced that black people were more fun and moral. I felt I related more to latino children culturally but this could have been a class thing because i got along with white children or related to some also. I think that I watched PBS alot and liberal news that conditioned me this way. Still I was pretty aloof as a child. Alot of these thoughts i had as a young person could have been because I was catholic and went to a Catholic school. Looking back, it was a bit more diverse than the whole of the valley. 

So, perhaps this was personal experience and some of it was propagnada. I cant figure it out. Now i pretty much know that all people have similar morality and are fun, but that there is definitely a class war which has casualties on both sides and white supremacy order at the historical heart of American Empire that incorporates diversity still to the project of what it sees as civilizational evolution.
