Make derogatory comments about women and question the legitimacy of the recipient's profession based on their arguments.
I spent 8 years teaching women how NOT to end up in court - unless on the other end of an assault charge where they had ripped a shin or the lower lip, or smashed the two fine nose bones right into the brain... Toughest problem was overcoming women's revulsion at the simple yet very effective techniques.  I remember one young female idiot who insisted on walking through a dark park at night to get home. Said it was her 'right'. Sure enough, she was attacked one evening. She fought her assailant off. Never forgot her feminist arrogance. 
Speaking of which...
I can believe you were a lawyer who defended such idiots. No doubt you remember the true story about the NYC cop cross-examined in court by a Defence Attorney as to why he locked his locker at work if he really trusted his fellow cops? The cop's response: "Sometimes lawyers walk through our locker room."
Based on your 'arguments' and reactions on this site, I have difficulty believing it was the opposing counsel who were clueless.
