But it's precisely when humor is offensive that we need it most. Comedy should provoke. It should blast through prejudices, challenge preconceptions.
Comedy should always leave you different than when it found you. Sure humor can hurt even alienate but the risk is better than the alternative; a steady diet of innocuous, child proof, flavorless mush.
Demand to be challenged, to be offended, to be treated like thinking, reasoning adults and raise your children to be the same.
Don't let a comedian, a network, a congressional committee, or an evil genius take away your freedom to laugh at whatever you want.
