We have always been a country of different folks who had a hard time getting along. Look at Rhode Island. Puritans would prision and flail Quakers. Franklin had to argue with Quakers to support defending other settlers. Not to mention the civil war. So we have always had strife. Various little rebellions.
The last 70 or so years have been a bit differnt. WWII, integration of the military, civil rights movement gave us hope that we could overcome these inherit difficulties.
Doesn't seem to be going so well today. But it has been worse, and there is fall we can do about it outside of living the life we admire. For perspective we are lots better off than Yugoslavia, Syria, Libia and a whole host of other countries.
The "news" sells hype, adrenaline. Not that one should go asleep, situational awareness is good. But that also entails accurate diagnosois of the threat.
