The author is correct as far as hurting and killing animals is morally wrong.

And yes, Runner, killing human babies is also morally wrong.

This however, doesn't authorise the state, one of the least moral bodies in existence, to impose itself as kind of a "moral guardian", enforcing moral codes over the people who live in "its" territory.

Both the author and the churches are more than welcome to put forward their moral convictions in every possible forum in order to try and peacefully convince others of their views, as well as to use other non-violent methods (including naming-and-shaming and boycotts) against the perpetrators. However, using the brute force of the state and its laws is immoral in itself, so there it must stop.
