SD, answers 1)  if the request to put on garter belt included a threat of employment consequence, then a complaint is not petty.  If it was just a request with no enforcement implied, then the complaint is petty (IMHO); 2) If he threatened to fire if sex was not agreed to, the complaint is not petty; 3) If the request to kneel included threats of employment consequence in absence of compliance, a complaint is warranted.  The complaints seem petty to me because in what I read, the man only made comments rather than using his position obtain compliance.  

My point is that rational analysis of situations rather than emotional, PC, reaction is desired.  If the women are truly just punishing the man for non-PC thinking, they should be ashamed for disrespecting the intellectual freedom of others.  If the man, used his position to actually force women to do his bidding, then he is seriously at fault.  Trying to figure these things out with sloppy journalism and high emotion is a challenge.
