That's nice and welcome, unfortunately the cult has stolen the minds and love of so many. They being members of the cult have lost all rational thought and being told thier in gods only true religion has made them arrogant in thier attitude. A person can show a JW the obvious problem with saying god wants us to kill our selves by not taking blood but cows blood is ok and they'll still not get it.
So despite your love your parents probably never get a clue or wake up, so don't risk your kids!!
