Well, if you want an honest true response, I'm going to give you one...but I'm not sure if you're going to like it.
Before Obama, racism was not crazy as it is now. When Obama took over and there were some racial tensions, he would actually escalate it and make it worse. He created a divide. That divide got worse...i mean, im sure you've seen what's been going on lately.
i follow enough news (I do not follow mainstream media because they're so biased and omit so much for click-bait. Its embarrassing) to know that it started to get worse because of extreme race baiting through the media.
The media benefits from this. They were very quickly getting less followers, less watchers, and losing money. So they do clickbait articles, race-bait, and get more money out of it. I've read a lot of the titles of articles and news lately, and they all sound racist, and they only cover racism. They cover divide.
I remember this quote: the more you feed negative energy, the more powerful it becomes. The more we concentrated on it, the more we exaggerated racism, the worse it became.
It's almost a self-fulling prophecy.
I'm not saying racism never existed, don't be silly, it did...but I saw an extreme increase of it these few years.
The extreme left acted racist towards the whites (yes, you can be racist to anyone, including your own race - that's the one lie that the left needs to get rid of and understand), and so the whites on the extreme right retaliated.
This was very "eloquently" shown in Chartlottesville. The extreme right ("white supremacists") got a permit to protest peaceably (no matter how much anyone disagrees with any group, peaceable assembly is protected under the first amendment), but the extreme left (ANTIFA, BLM, SJW, etc) decided to interfere...and the damn cops didn't even do their damn jobs. They could have prevented this, but all they did was allow the left to co-op the protest, tried to unlawfully shut it down while it was peaceful, then barely even did anything when it got violent.
I support any peaceful protest, but the moment it gets violent, EVERY COP should do EVERYTHING in their power to stop it. It was neglect on their part. This whole thing was a mess....and it will most definitely cause more friction between not only races, but also both political sides.
At the moment, I think the biggest problem is political ideology..and how people immediately assume the worst of either side from 1 simple "I'm a liberal "im a republican".
