As a Christian I'm against abortion. As a liberty-minded person I'm against legislating my anti-abortion beliefs on to people. Christians teach their kids not to gossip, lie, covet, etc. without advocating laws against those actions. I don't see why they can't do the same thing with the subject of abortion.
Did Jesus lobby the Roman Senate to pass laws that require people to act like Christians? No. He just said, "This is the way I live. It would be good if everyone followed my example. Now choose for yourselves."
The reason everyone hates the church is because in modern times they've been trying to outlaw abortion, profanity, drinking, gay marriage, etc.
It's why I don't go to a church anymore.
