The holocaust is an event that resulted in 6 million people being murdered.  It was an attempted genocide.

 

I don't see how any cartoon can compare to that.  If they are the same thing to you, then that speaks volumes about you.

 

Now, let's assume you could prove that the holocaust did not happen - in that case I would defend your right to speak out about it.  But you can't because it is a story that antisemites use to justify their bigotry.

 

Two wrongs don't make a right, and so your argument is moot.  Having said that, freedom of speech is a right that many believed was under threat by President Bush, and you are right when you say that it is under threat in the west.  Freedom of speech is like all other rights - they will always be under threat from some people who would chose to do away with them in their quest to accumulate more wealth and power.
