Those people are idiots too. It doesnt take 1000lbs of energy to kill a deer with a rifle. A lot of deer have been poached with a single .22 shot to the neck. With bow 40lbs of ke is plenty. I would shoot a small dia cut on contact broadhead. Maybe a two blade magnus. 2 blade heads penatrate deeper with low ke set ups, due to less resistance drom only having two blades. I killed my first few deer shooting a 35lb bow and 3 blade muzzys, my ke from that set up was maybe 25-30lbs of ke. Shot placment is KEY. What weight arrow are you shooting and velocity?
