Lashon Ha-Ra on Chaim Nachman Bialik

Q: Is it permissible to speak Lashon Ha-Rav about Chaim Nachman Bialik?
A: No, it is forbidden to speak Lashon Ha-Ra about a Jew. It is true that this Jew learned in the Volozhin Yeshiva and later did not observe the mitzvot, but he did believe in Hashem. In Tel Aviv, he battled to give the city a Shabbat atmosphere. He said that it is not enough to excommunicate others and throw stones, so he organized Shabbat get-togethers and he would not smoke there. His "Sefer Aggadah," in which he collects and organizes the midrashim, is very good. He also felt a great responsibility for the Nation of Israel to the extent that people refer to him as the "National Poet." He did not write to make a name for himself or for the mere pleasure of writing, but he worked to be a mouthpiece for the serious national problems with the aid of his writing and poems. He was a complex person and included both lights and shadows, and why should we speak Lashon Ha-Ra about him?
