Nah man. Remember, if things not supporting the thesis "IT'S A TEST FROM GOD/SIGN THAT YOU SHOULD CONVERT TO MY RELIGION AND BELIEVE IN MY GOD" but if things are going well/support the thesis then "IT'S GOD'S BLESSINGS/PLAN FOR YOU BECAUSE YOU ARE A BELIEVER!!!!"
I don't actually care if it makes people's lives better and/or their being objectively "better" people if they believe in whatever they want to. In fact, if a belief system had such a result in every case I would probably be in favour of everyone having such a belief system. What I object to is people foisting their personal beliefs on me, or claiming that my belief system (if any) is somehow less valid and theirs is superior using facile reasoning such as the above.
