I have gotten more 1000 yard stares over the years from 150lbs massive juicehead twinks who think they are bodybuilders than any powerlifters.
If anything the bigger the lifter(powerlifter, bodybuilder, weightlifter, etc) typically my experience is they tended to be nicer to not only me but everyone
