By all means, dust off that resume because there are GOOD companies out there looking for good people. But you are the only one who can determine whether you should stay or go. Your walk talks and your talk talks, but your walk talks much louder than your talk talks. Be known as a person of good character, be a professional, be there to help and not criticize. Ignorance is, in fact, curable.
Stupidity is forever, though.
If they're stupid, bail out. If they're ignorant, try to help first. Character is used in the assessment for candidates for promotion. Character is also used for employee recognition. Recognition based on character rather than achievement.
