The paedophillia aspects are covered in another law... though if you have violent pornography of children you may be prosecuted under two laws...

Oscar Wilde (afaik) was imprisoned for the crime of homosexuality rather than anything under the pornography laws. After this, homosexuality moved from being a crime to a mental abberation (which allowed you to be sectioned under the mental health act) and finally to the acceptable sexual choice it is today. And speaking of bizarre sexuality based laws, are you aware that it was illegal to be a male homosexual but not a lesbian because (to quote Queen Victoria) 'ladies don't do those things'. She refused to sign the law making lesbianism illegal as well as male homosexuality for that very reason.

It is interesting to get better definitions of what they mean by 'violent' as well. Very useful to know.
