Right, asking questions, raising concerns, informing yourself are good. No one here on this board that I've seen is suggesting blind faith.
Real experts and specialists trained and experienced in specific areas can help inform people in how to be a responsible citizen, how to make good decisions for themselves, their families and people they care about knowing the benefit/risks involved.
