Chayav inish livisumay:
To address your first post, Joker Bar Daddy’s original question indicated that in all yeshivos besides for Chofetz Chaim, Mussar is not part of the curriculum (or at least that is his perception). I have no idea if that is true or not, but my first response was to provide a reason why a yeshiva would not have mussar – i.e. a possible defense for all the yeshivos that don’t have mussar. You can’t argue against me that R’ Chaim is irrelevant by virtue of the fact that all yeshivos learn mussar, if my whole usage of R’ Chaim was to explain the yeshivos which don’t learn mussar. If in fact all yeshivos do learn mussar, then that would indicate that R’ Chaim’s position was not accepted, or that the level of sickness has changed and my justification would be unnecessary and we could simply tell Joker Bar Daddy that it is indeed just him.
Your second post is addressing a different point that I made which is that the idea of an institutionalized mussar seder does not seem to jive with how the Chofetz Chaim viewed mussar. Even if everyone agrees that everyone needs mussar, that doesn’t mean that everyone’s mussar needs are the same. But I acknowledged that it might not be practical to have individualized mussar.
