Most of its members say one thing in their comments at the meetings, preach one thing in service, and pray yet another to their god. But on the whole most jw's get drunk, have sex or "fool around" before marriage, get involved in some type of drugs (weed), lie. And these practices are done on a regular basis by most jw's at one time or another without ever coming forward.
