I just heard another one of those arguments against capital punishment that goes like this: "If we are really against killing, then you have to be against capital punishment because it is a kind of killing."
It is fine with me to abolish capital punishment, but this argument is so pitiful.
1. When we make murder illegal (and punishable at all) we are not opposing all killing, only the kind that qualifies as murder.
To say all killing is equivalent is as foolish as saying all sex is equivalent.
2. If X imprisons someone and is sentenced to prison himself, what do those who use the argument above say about that? Do they say: "If we are really against imprisonment, then you have to be against sending X to prison, too."
It is ironic that they are inconsistent about applying their consistency argument.
