Everything you can write or draw offends someone. Whether it is meaningful political dialogue or an ugly parody, the United States
has had a tradition of free speech. Want to make fun of the King of England, the President of the United States, make an outrageous caricature of a politician you dislike? You can do it, and the 1st Amendment to the Constitution protects your right to do so.
Don’t think much of the President, make him look like a monkey. Don’t like the Vice-President, have the feeling he is evil incarnate? Dress him up in PhotoShop to look like the devil. Want to make a comment on the recent Republican candidate for Vice-President? Slap a pig nose on her face and get all your friends to say what an artistic and insightful guy you are. But if you dislike the Obamas, you better just keep it to yourself. No PhotoShop for you, you racist. Satire not permitted.
If we don’t believe in freedom of expression for people we despise, we don’t believe in it at all.
