You started this discussion saying "it's reasonable" but you're unwilling to give any reasons beyond "I believe it is sinful". Instead of engaging with any of the positions I put forward, you went on a tangent about crack without saying why it is at all similar or why it would be morally wrong even if it were. I don't believe you're stupid enough to think that that really carries any logical weight as an argument, so yeah, the only remaining conclusion I can make is that it's bigotry instead.
