Perhaps, the title of my question sounds amusing, but I see this happen in my shul a bit too often for me to laugh at it any more. Many of the Bar Mitzvah boys in my shul can barely read Hebrew. but, to make the boy and the family feel good, they ask him to return the Torah to the ark. The boy says, "Yechalelu et shem Hashem", meaning, "Let us PROFANE G-d's name" instead of the real word which is "Yehalelu et shem Hashem" - "LET US PRAISE G-d's name."
Seems to me that the mispronunciation is serious as it is not just incorrect, but makes a real mockery (even unintentional) of what the phrase should be. But, no one says anything because no one wants to embarass the boy or the family by correcting him. Should we let it go, or correct him?
