portableniche 

Started online by child pornography advocates but moved to freedom of speech and expression arguments to justify their beliefs

He's making the classic "portableniche" argument but just because something can be said doesn't mean it should be said.
OMG you're a "portableniche piss stain"

Someone who believes the freedom to say anything regardless of the racist or homophobic meanings.
