STOP THIS HERESY ABOUT JESUS CHRIST!

Thank you beloved reader. I have not made this write up too long which would discourage you from reading to the end, so I have tried to make it compact enough and hoping you would understand and also get triggered to study more on the subject.
I do not have problems with people who get angry easily nor people with anger traits like the people of Ondo, Ekiti, Calabar, Warri, etc, however, I do have problems with those who claim to be christians, yet get angry, some even boasting about it with pride. [e.g A christian saying, "I'll let you know I'm from Ondo" while having a clash with someone]. My question then is, SHOULD A CHRISTIAN GET ANGRY OR NOT?
Well, many answers have been given to the question, some of which are "Jesus got angry at the temple gate"; "Jesus got angry with the fig tree" Paul wrote, "Be ye angry but do not sin"; "Peter got angry with a soldier at the arrest point of Jesus" and many others, just to site a few.
From my study on the subject and with the few points highlighted below, I strongly believe a christian should never get angry, no matter the circumstance, though I stand to be corrected.

1. Anger is an act of the flesh (Gal. 5:20) and whoever still found in the act is not born of the Spirit, hence, not born again. That is, not a Christian. John 3:3-6.
2. Jesus never got angry, He only showed acts of displeasure which is not equal to anger. Jesus' acts can be related to the statement "humility is not stupidity". God in the new testament was a God of grace for mercy compared to the God of law and Judgement of the old testament".
3. Paul wasn't supporting anger in Eph 4:27; reading a simpler version like The Living Bible would be helpful, and for those who stick to KJV, I think you all ignore the 31st verse of the same passage. Try reading the whole book of Ephesians carefully again and also look into Paul's statement in Col. 3:8.
4. Anger does not bring about the righteous life that God desires. [James 1:20, NIV] and by this we tell if we are children of God or of the devil. See 1 John 3:10.
Since after the death and resurrection of Jesus Christ, I couldn't find any of his disciples who got angry at any point, not even Peter who used to be hot-tempered. No, not one.
I could go on and on, but I want to stop here and I hope you would share this with as many as you can in a bid to stop this heresy about anger especially amongst christians of today that we may live the truth we preach.
