I myself do not agree with this boycott as I believe that meaningful freedom of speech and expression cannot exist without a willingness to tolerate speech that you may find offensive.

However, I do not agree that the boycott is essentially racist, even if some of those supporting it are using racist language in their posts. (Some black activists have made some inflammatory comments about assassinating whites and policemen, but this hardly proves that black activism is a terrorist movement at heart). It is also a bit disingenuous itself to suggest that the show targets all racial groups equally when the title singles out whites.  As for white people's greater willingness to accept Stephen Colbert mocking white people, all racial and ethnic groups are more accepting of satire and criticism if it is coming from people with the same background as themselves.
