“It is our attitude toward free thought and free expression that will determine our fate. There must be no limit on the range of temperate discussion, no limits on thought. No subject must be taboo. No censor must preside at our assemblies.”

Oh, and don't forget to be politically correct.(Sarcasm here).

I wonder what he would think of "hate speech" and "hate crimes"? Now it matters what we say (above and beyond libel) and murder isn't just murder. It matters what a person thinks during the murder. Somehow killing one person is more heinous than killing another based on ethnicity, sexual orientation, etc?

In context, absolutely ! In a bigger picture, the rejection of static law, as was understood through the laws of nature and of nature's God, will also bring about a most to all destruction of freedom's expressions.
