Freedom of speech is not freedom from criticism.
From Walter E. Williams:
It's always been my contention that the conservative vision shows far greater respect for blacks than the liberal you-can't-make-it-without-us vision. For decades there have been buy-off-the-black-vote presidential appointments like secretaries of labor, health and human services, education, and housing. But it's been conservative presidents who have appointed blacks to top positions of responsibility and authority such as Secretary of State, National Security Advisor, Chairman of the Joint Chiefs of Staff. Republican presidents didn't make these appointments to buy off the black vote. They chose the best people around who just happened to be black Americans. Conservatives, Liberals and Blacks
These dopey kids had a right to protest, but they missed a golden opportunity. I've sat through hundreds of live speeches by people whose politics I abhor - everyone from Barack Obama to Madeline Albright to Tom Daschle to Michael Dukakis to Walter Mondale, and on and on. And every single time I did, I took something away from it - I learned something. Damn shame these kids blew this opportunity. I guess they're too wrapped up in The Vagina Monologues, Justin Bieber and other useless ****. No wonder they come out of school and can't find jobs.
