If the Church believes their teachings are correct, it seems logical that it should be doing more to enforce them. And yes, I have the right to express that opinion---just as you did as in "...find themselves another faith...".
Changes in some laws have certainly been discussed, even by priests and bishops. I doubt if anyone (I included) has suggested that every teaching should be abandoned! I hope you realize that you jump to your own thoughtless conclusions.
I never said I want the Church to "say murder is OK." Nor did I even intimate that it should condone homosexual marriage. Where do you come up with this stuff?
If a Catholic can not abide by each and every teaching of the Catholic Church they need to find a protestant faith that suits them.
