Ok, you don't agree with the Church's teaching on abortion, fair enough.
Women are free under the law to kill their unborn children for whatever reason, it is up to them whether they heed the Word of God or ignore it. The punishment will probably not be in this life although it sometimes is but it most certainly will be in the next. The Church simply points out the eternal consequences of this choice.
The Church does not have the back up from most secular authorities anymore to preserve a Christian state. That, however, does not mean, that the Church should keep its mouth shut and not be an advocate for Christian morality.
