Pretty much. One of the ways LDS leadership keep the rank and file in line is by threatening them that if they do too much research or read non-LDS literature (esp religious), then they will ‘think themselves out of the Church’ or ‘lose their testimony’. Last year (IIRC) one of their leaders at conference stated that the goal of ‘antis’ was to make them lose their ‘testimony’ of the ‘restored Gospel’ and ‘Joseph Smith’. My response? Yep that is exactly my goal - to get people out of Mormonism and to Christ.
What was it like when you first started doubting the Mormon church?
