I agree, Baptists really get a working over from other denominations, always have, always will.
I think a lot of it is jealousy. See, all Baptist churches have or have access to swimming pools instead of those shallow baptismal fonts that look like bird baths. Who can ever remember being sprinkled as an infant or even as an adult but no one forgets baptism by immersion, especially in a cold lake, stream or when someone forgets to turn the hot water on in the baptismal tank (that's for us northerners).
