18 yrs old, college smartass [in contrast to middle aged
   smartass?] I loved to go around to my Tolerant friends, waxing
   poetic about their tolerance. All I had to say is: *"If you're
   so tolerant, are you tolerant of intolerant people, because if
   you're only tolerant of tolerant people, you're more intolerant
   than them." The resulting social melee was priceless.* They were
   so busy feeling superior they didn't stop to think how
   intolerant THEY were being. Yeah, I was/am a prick sometimes. :)
