These days it's become such a truism that you're generally considered an extremist if you disagree.
But have you ever considered how, if that statement is logicially valid, it must be equally applicable to extremist religions like the Aum Shinrinko doomsday cult as to any other religion. That is, concrete application requires us to concretely affirm, "God can be realized through Aum Shinrinko. Aum Shinrinko is true." Would you be comfortable affirming that? Truly?
Personally I am far more comfortable with a far more modest affirmation, "There is truth to be found in all religious." But observe, this is not an affirmation that they all have the same truths. Nor is it an affirmation that they all have it in equal measure.
