Mitt was also a Stake President over the Boston area. He also served as Young Men's President and several other leadership positions. I encourage you to go somewhere other than the Mormon critic's websites for your knowledge of the church.
LDS.org leaps to mind. Straight from the horse's mouth, as it were. Then decide for yourself. Getting information about the church from other religions and the critic's websites is like going to a Ford dealership and asking them if you should buy a Chevy. You're not going to get a straight answer.
