Forgiving Someone who was Disrespectful to a Rabbi

Question: In the community where I live, there is someone who was disrespectful to the Rabbi, and I can't even talk to him. He does not seem to regret what he did, and I don't think that he will accept my rebuke. Do I have to or am I permitted to forgive him?
Answer: This is not your honor, it is the Torah's honor. We are not obligated to forgive someone who has not requested forgiveness. You are allowed to forgive someone who has done something to you. If you have a good heart, you can forgive him. This is an act of piety. Here, he was not disrespectful to you, he was disrespectful to the Rabbi, and you therefore cannot forgive him in place of the Rabbi. If you are angry with him in your heart, you have to tell him that you are upset for this or that reason. This is like what Rashi says about Yosef's brothers. The Torah says that they could not speak to him peacefully, and Rashi explains that out of their shame, you learn their praise: They did not speak to him one way, but feel differently in their heart (Bereshit 37:4). It is even worse for someone who shames a Torah scholar. There is no cure for his ailment. In the Gemara in Baba Metzia (84b), Rabbi Elezar the son of the Rashbi

died, and they laid him on a slab in the attic for many years. One day, they saw a worm came out of his ear, and they were surprised. He came to them in a dream and said that it was because he once heard a Torah scholar shamed and did not protest. On such things, we need to protest. We need to protest everything which is against the Torah, but this in particular. Shaming a Torah scholar is not only his shame, but the shame of the Torah. Disputes and disagreements are acceptable, but not shaming. It is written in the books that Torah scholars do not want to discuss this subject, because then people will say that they are saying it for their own benefit. Torah scholars therefore do not talk about this, but it is very severe. The Gemara in Sanhedrin (99b) says that a heretic is one who shames a Torah scholar. The Talmud Yerushalmi (Sanhedrin 10:1) compares this to a structure of stones: If one stone is shaken, the entire structure is shaken (Jerusalem Talmud, Sanhedrin 10:1). That is to say, one who scorns any Torah scholar, knocks over the entire building of the Oral Torah in Israel. The Radvaz (vol. 4 #187) writes that even a Torah scholar who errs should not be shamed. His proof is from the Gemara in Sanhedrin (99a) that a Torah scholar named Rabbi Hillel – not Hillel the Elder – said that the Messiah will not come. Rav Yosef said: May Hashem forgive his sin and he brought proofs. Rav Yosef spoke to him in the third person with honor, and said that he erred and should be forgiven, because the damage done by shaming him would be much worse than the damage done by him saying that the Messiah will not come!
