Meh... most people are dumb and biased. Let them be dumb. Natural selection will weed them out.
Personally, I have much respect for any champ/contender who takes a defense against a "shit" opponent and risks it all for basically no reward other than a paycheck and the hope that their next opponent is someone better. At the end of the day, yes -- if you're trying to assess someone's legacy you have to weigh the strength of their schedule... but GSP having to fight Jake Shields, Anderson fighting Thales Leites, Jones fighting Anthony Smith... sometimes you've just gotta take care of business. Those guys all earned their shots, uninspiring as they were, and those champs proved themselves when they needed to against the best of their division. Al earned his chance... fuck the haters. Better to stay busy than sit on the sidelines.
