But from the books of Musar we can that there are kinds of joy that are bad. rrect.
As Steven Dutch writes God's Grandchildren : Some will adhere to the established religion out of sincere conviction but will disagree with important tenets. They will attempt to recast the religion in more personally palatable terms, or possibly work to redirect the religion itself into more agreeable lines. The changes may be real reforms or merely redefinition into something more palatable.

That is a recasting to redirect things  is honest in itself as long as the basic principles of the religion are preserved. That is Steven Dutch's opinion and it makes sense to me.
