I know nothing of 20K denominations you mention. But I'd rather side with liberty and free debate over hermaneutical issues, than have people drowned and burnt at the stake because they didn't subscribe to a central authority telling them what Scripture says. And it worked out quite well for the establishment of this country, in searching for a place to freely worship God as an act of conscience, and not by obligation.
wern't the Salem witch trials held by protestants in this country ??
