It seems to me that the author is actually a proponent of censorship. While there are limits to our First Amendment freedoms (no shouting "Fire!" in a theatre, limits on access to pornography, etc.), actually stating that because something is racist and that it should not be published is a dangerous path to take.
Censorship should never be an option. Someone's feelings were hurt? So what? That's something you learned how to deal with as a child (or should have). Normally, humans grow up and mature, and we get over it. It's the sign of an evolved sensibility to be able to take something negative and turn it into a positive. Education and diplomacy should be the rule of thumb in the aftermath of a situation like this.
