Excellent point, I am reminded of Galatians 2:11-21, which I am now reading with new eyes.

Galatians 2:11-21
11 When Cephas came to Antioch, I opposed him to his face, because he stood condemned. 12 For before certain men came from James, he used to eat with the Gentiles. But when they arrived, he began to draw back and separate himself from the Gentiles because he was afraid of those who belonged to the circumcision group. 13 The other Jews joined him in his hypocrisy, so that by their hypocrisy even Barnabas was led astray.

14 When I saw that they were not acting in line with the truth of the gospel, I said to Cephas in front of them all,

“You are a Jew, yet you live like a Gentile and not like a Jew. How is it, then, that you force Gentiles to follow Jewish customs?

15 “We who are Jews by birth and not sinful Gentiles 16 know that a person is not justified by the works of the law, but by faith in Jesus Christ. So we, too, have put our faith in Christ Jesus that we may be justified by faith in[d] Christ and not by the works of the law, because by the works of the law no one will be justified.

17 “But if, in seeking to be justified in Christ, we Jews find ourselves also among the sinners, doesn’t that mean that Christ promotes sin? Absolutely not! 18 If I rebuild what I destroyed, then I really would be a lawbreaker.

19 “For through the law I died to the law so that I might live for God. 20 I have been crucified with Christ and I no longer live, but Christ lives in me. The life I now live in the body, I live by faith in the Son of God, who loved me and gave himself for me. 21 I do not set aside the grace of God, for if righteousness could be gained through the law, Christ died for nothing!”[e]

If Paul was so forthright with his objections to Peter, the leader of the apostles of all people, then we should be forthright with our objections. Boldness and courage it seems are virtues when dealing with errant doctrine.

Somehow this is also a gentle rebuke by Paul to Peter. Given 2 Timothy 2:25-26:

25 Opponents must be gently instructed, in the hope that God will grant them repentance leading them to a knowledge of the truth, 26 and that they will come to their senses and escape from the trap of the devil, who has taken them captive to do his will.
