Problem is, you assume someone like you will determine what is offensive speech. Far more likely someone like Obama will determine what is offensive and use the power of the IRS to shut it down. Oh, wait. That’s already happened.
Yes. Obama is a problem. The idea that Hebdo Charlie is protected speech is another problem.
Obama, however, is a product of a certain culture, the kind where Chicago thuggery is normal politics. In other words, a cultural and legal problem, — what is free speech and what is trash, — gives us a country where Obamas can get elected and re-elected. I propose we strike the root.
No, nearly anyone can tell the difference between insults and speech. Courts make more subtle determinations daily, and for the most part we trust them.
