Racism in the media

Freedom of speech allows people to take liberties with mocking Asian Americans.  Would the examples below be tolerated for other racial groups?

Here are examples of everyday folks with their tweets:  http://publicshaming.tumblr.com/post/54791337536/idiots-use-plane-crash-in-san-francisco-to-mock-asians

What is the role of the media in modern-day racism?  http://criticalspontaneity.com/2013/07/07/asiana-crash-the-role-of-media-in-modern-day-racism/

Sometimes there is a fine line between distasteful and blatant racism.  Check out this Chicago Sun Times headliner:  http://www.huffingtonpost.com/2013/07/08/chicago-sun-times-san-francisco-headline_n_3562177.html

Racism towards Asians among the media is not limited to this latest incident of the Asiana crash.  The so called “progressive” radio talk show host, Stephanie Miller and her sidekick, Jim Ward, made fun of Asians when they mimicked Kim Jong Il's accent:  http://www.youtube.com/watch?v=yJiLdatYhwY

Everyone is encouraged to speak out against such behaviors.  Call in to radio stations.  Write op-eds.  Comment on tweets, etc.  Any other suggestions for how to deal with such behaviors?
