People who are honest, sane, and not profoundly mentally deficient learn something when people tell them it over, over, and over again.
You mean the people who pray to dead people for help from God, believe that one just has to follow their conscience to go to heaven, and keep track of how many times they pray to God's mother on a set of beads. Not to mention completely ignoring the first 600 years of Church writings, councils and creeds relegating the early fathers to the status of "mystical", "bigots", and "ignorant". And these are the people I'm to learn from?
