Social division, that’s called social media lol. People arguing just to argue. Whether they truly believe in it or are just having a bad day or just trying to stir up trouble. You’ll never get unity in any country never mind the USA. There’s to many issues people get fixated on and refuse to look at the whole picture. Example Chicago black on black killings daily it’s like a war zone, no ones fixing it or really talking about it. Racist white cops shooting people of color , it’s truly a serious issue, but the media pours it on for ratings. The whole Native American thing, I’m 99% sure they traced there dna back to Serbia and Russia, so are they Native American or Eastern European. There just to many issues out there. Even for instance Iran attacked us tomorrow, and we attacked back. Half of the USA would be all for it. The other half would be bitching at Trump for killing innocent people over there instead of worrying about the lives over year. We live in a twisted world, it’s best to just ignore everything and focus on your own life and that’s it.
