Be that as it may, there is a legal difference between the two. I'm not arguing that there shouldn't be (That's bill's argument), just that there is a difference and it is significant.
As for the innuendo and outright accusation that bill is a pedophile that is being spewed by you and izzy, I would suggest that you knock it off unless you have some proof, which of course you do not. Neither of you know who he actually is and unless he has posted a confession, your allegations are not only without merit, they are foul. It is one thing to suggest or assert that someone is wrong, or stupid or an asshole, it is quite another to allege they are sexually perverted and a criminal. It doesn't even have a bearing on the argument at hand. There are plenty of people who don't believe sex offenders should receive additional punishment (appearing on public sex offender lists) after serving their sentences. Do you assume they are sex offenders?
Has bill ever started a thread titled "Why I like kiddy porn?" Or posted that is was acceptable and should not be illegal. There are people out there who might, and guess what? They are far more likely to share your political views than mine. It would be ridiculous to draw conclusions about you based on that.
Your side of this argument is by no means either specious or foolish. Why not stick to that and leave out the crap about liking rape pictures?
