Friend, there is only one kind of dumb question: those that are statements with a question marks at the end of are simply a vehicle to place a statement.

And even those are fine by me if the asking being realizes this within the discussion. (“Why are we allowing women to vote if they are that much dumber than men?” is a stupid question in my book - and even that can lead to “oh wow I always just assumed that to be true but (data/argument) made me realize that I was wrong!”. Rare but can happen…)
