Aggie, A reasonable person would view child pornography as a crime not a right of self expression.

I am of the mind that your personal freedoms end when your fist meets my face. Being insulted, made uncomfortable or having some personal disagreement is insufficient cause to prohibit artistic expression. The first test should be material harm and that should require heavy qualification. Free speech is just to dingdang important.
