Anger

So while not everybody agrees on the Bible (that's kind of the point of origin of America's different thought processes and philosophies, each denomination disagreeing on what the Bible meant, but having the freedom and the legal structure to do so wonderfully without the wars of the past), it will be pointed out that many people still believe its teachings both as believers and as a point of philosophy. Here is one of those masterful quotes:

21 ¶ Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment:

22 But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.

23 Therefore if thou bring thy gift to the altar, and there rememberest that thy brother hath ought against thee;

24 Leave there thy gift before the altar, and go thy way; first be reconciled to thy brother, and then come and offer thy gift.

(Matthew 5: 21-24)

In a society of people where people kill for traffic violations, or rant and rave and troll on social media,  and that temper is getting shorter and shorter, we need to watch our thoughts, desires, and actions in order to make sure we do not let that anger, or the logic of our ideas get in the way of our relationships with our family, our friends, our countrymen, our leaders. To simplify the Master's teaching in essence, fix the problem now in person, talk to someone about their post(s) in person without getting angry, and calm down. There are by far more important things in life than you being right.
