Its not lame at all, the problem is when someone is told to act like someone greater than them, and they fail, many times the con sequences are worse.
If someone cannot live up to be the Chofetz Chaim (Which they cant) they might give up saying its too hard (Making things too hard only creates opportunties for failure) . Better to live up to your best and not the Chofetz Chaim, You can succeed at being your best, you cannot succeed at being the Chofetz Chaim
