This is police state discrimination. The politically correct crowd wish to outlaw opposition to native land claims or massive immigration. To that I add the words of Clayton Ruby in response to David Matas, one of the more extreme and intolerant promoters of things Jewish, always the first to censor - and always the first to wail. Its corollary, I suppose, is that if you can force people to say words that promote good ideas, you will promote the good. Both notions are false.
Words have no such magic.
That did not prevent changing social, economic and political ideas from having their inexorable way. Mr. Matas is a distinguished scholar and lawyer, and I know his heart is good. But the banning of hate speech carries a huge cost. And it is futile.
