I think for some folks that is true, but I know really solid guys who stick their noses high in the air when you mention MacArthur. When you ask why, they will always prevaricate and say something to the effect of "I don't want to speak ill of a brother in Christ, but I dislike his work" and refuse to elaborate.
I know he puts the smackdown on charismatics, but these guys aren't charismatic.
