Intermixing races

I have been hearing this a lot lately,

how certain races are often blamed for our own mistakes, 

I don't understand it, I thought we had already moved passed it!

I mean come on can't we all just get along, the last I checked the war has already passed!

People say we should move on, but I know that some people won't change at least not without some modest persuasion.

I am tired of the lies and false accusations!

I am tired of hearing about this everyday!

I am tired of not hearing the good things that come of intermixing of different races! 

Our ancestors did it, why is it so bad now? 

I don't understand why we can connect with the people who are here now regardless of race, why is it so terrible, horrible, and indescribable?

I just want everyone to get along and last I checked we were.
