That law was effectively overturned by the Supreme Court. In Britain, opponents are arguing that the comic book industry would be destroyed by such laws, because even mainstream comics like Batman, Judge Dredd, and much of Japanese Manga would fall under the ambiguous and overly harsh blanket censorship. The British government apparently defines an ``extreme image'' as any ``grossly offensive, disgusting or otherwise obscene'' moving or still depiction of someone any ``reasonable person'' would think real being sexually injured or engaging in sexual activity with an animal or corpse. (Because, you know, fictional corpses have rights, too!)
If you live in Britain, you might want to protest against this outrageous invasion of privacy, this blatant oppression and censorship based on religious extremism and fear.
