I have to say I haven't read much Calvin, but if this is an example of his "reasoning", I don't understand why anyone would follow him.

You can distill his argument into this analogy:

Some people hurt themselves with hammers. Those who provide hammers know this. Even those who skillfully use hammers for other purposes might hit their thumb too. We know, and admit that this is a rarity. However, we should ignore any other uses hammers may have besides hurting people - they must be banned from everyone and those who provided them prosecuted.

Does that about sum up his reasoning?

You have a pretty good grasp of Calvin. ;O)
