Nobody here has been approving of child porn. Rick wasn't talking about child porn. The subject is porn involving consenting adults, and the point of many of us is that porn IS NOT the most pressing issue facing the US today, higher than illegal immigration, higher than the dangers of Islamic jihad, higher than the economy, etc.
As for the 'consenting adults,' the majority of women in porn are there because they were abused as girls, or prostituted.
As much as amoralists would like to disassociate pornography from sexual abuse, it's directly related, and therefore a concern.
