Remember when Liberals were all about questioning authority, ant-censorship and free speech? Now if you question our government you are racist. Events in history are being erased (censored) in the name of political correctness (take the case of ESPN cutting out Curt Schillings game play from broadcast). The new wave Liberals need safe spaces to protect them from speech they don't like.
I guess I'm old but people saying things has never scared me. Now the thought of not being able to respond to those people saying things is another story. The answer to speech you don't like should never be shutting out what other people have to say but to rebut it. If you don't have a strong enough stance to do so, you should listen and learn and examine your own stance not run away to where there will be cookies and puppies and you don't have to think about anything.
