Phil – separately, I agree completely with the first paragraph, as does halacha and any adom gadol who has spoken out about rebuking others. regarding the second paragraph tho, I think you are correct that it is hypocritical to criticize others for things you regularly do. But he didn’t say that. He said that you can still preach doing what is right even if you yourself are deficient. I think there is a difference between preaching what is right, and criticizing others. I will not imply that I think Joseph’s methods are anything constructive, halachically appropriate or beneficial, but I do believe that your response does not correspond to his comment in that one issue.
