I didn't say there wasn't, I said blame "us". Just like unions divisions are two way. I can make a good argument on how your side eradicated their culture,excluded them from participating in society,ostracized them for holding their most sacred beliefs and painted their entire group as villains for the actions of the fringe. You allow them to participate so long as they abandon contradictory belief. They are terrified of you as you are of them. You stopped seeing them as equals, but as "impressionable" ,uneducated,gullible,foolish and ignorant. Blame yourself first. There have always been rush limbaughs,alex jones',and donald trumps. Evil and deception are not a new invention. Deep seated divisons and mistrust of this level are however new to your country. Even in the civil war era, they may have hated each other but they didn't consider each other subhuman, they did not think the union had an ulterior motive to eradicate them,the union knew the south wanted slavery,not world domination or some ulterior agenda against the masses.

I can't find a better comparison than yugoslavia ad Rwanda in the 90's if I wanted to compare america now with a historical country.

We can talk all day about this. The point is democracy does not mean the competent,the intelligent,the superior or those with the best ideas rule. It means the people as a whole (not in part) rule and give legitimacy to their rulers.

In other words, "they" certainly may be villains but "us" is what you need to fix. Why? Because everyone riding the same boat and everyone drowns when the boar sinks. That is the point if democracy and your boat is sinking. You will have no country to flee to because all your allies themselves depend your stability to be safe from your enemies.
