I don't see anyone "frowning upon" bodybuilding or "frothing at the mouth" regarding it. Just being realistic about what it entails. If you enjoy the sport of bodybuilding, then more power to you. It won't get you as much functional strength for a given amount of hard work as some other forms of training that are focused strictly on functional strength, but that's fine. As long as you get what you want out of the activity, that's what matters.
Powerlifters build pretty thorough whole body strength. For any strength related task you might want a bodybuilder to help you with, the powerlifter can probably bring more strength to the table. (I'm not a powerlifter, but I respect what they do.)
