Do you still consider NCIS a quality conservative show? I know it used to have that rep, but to my knowledge that rep as a good conservative show has badly faded over the years. Plus, I think characters like Abby and Ziva probably repulsed and revolted many conservatives to start with.
NCIS used to be one of my wife's favorite shows. I watched it for a while with her. Then I started noticing all the p.c. things on the show like the female computer wonk, the young juvenile males who were supposedly professionals but acted more like teen frat boys. One female character who was Harmon's boss (Lauren Holly) who left the show but only by killing umpteen terrorists single-handedly as she went out in a blaze of p.c. glory. The clincher was one episode about Muslim terrorist bombings. In a response to one character bemoaning Muslim terrorist bombings, Mark Harmon's character says "what about all the bombings of abortion clinics?" Right after that I almost threw a brick threw the tv screen. By the way, my wife never watches it anymore.
