Network TV would cease to exist if they couldn't make fun of white men and boys. The network "comedies" (if you can call them that - I think laughter is required to be called a comedy) are petrified to use women or blacks as the butt of a joke; rather both of those groups are usually portrayed as infallible. Offend either of those groups and face the backlash from the activists in the PC community.
