It is, in fact, the exact same thing: a temporary imprisonment enforced by the state in order to achieve its social goals. It is remarkable how creative the insults are in this thread, yet how utterly lacking in logic. The fact that you don't like the description doesn't make it wrong. The policy is the same, just implemented for different reasons and, we'd hope, with shorter periods of imprisonment. But that's what it is and name calling doesn't change what's being proposed.
