Sitcoms: Fun For Kids or Ruining Young Minds?

I was blasted for my recent commentary “Confessions of a TiVoholic” because I admitted I let my kids (ages 11 and 16) watch sitcoms. 

One reader went so far as to tell me that by letting my kids watch I was contributing to the foul mouthed culture of fifth graders who use the F word.

What do you think, are sitcoms  trash or just benign humor?

Which ones do you like, and which are contributing to the downfall of our moral values?
