"Conservatives are either stupid or evil" has been the Left's mantra for decades. Does anyone else remembers the Sixties news feature "Point / Counterpoint," with Jack Kilpatrick and Shana Alexander? You can trace the Left's thuggish behavior at least that far back.
Today, to counter the Mainstream Media, we have the Web, talk radio, and an assortment of conservative-oriented publishers. We also have some excellent "public intellectuals," such as Thomas Sowell and Victor Davis Hanson. We ARE "firing back" -- and Shapiro's recent book is a major cannonade in the effort.
Be not afraid.
