Social liberals are the ones that made single motherhood normal and then complain about how hard single mothers have it...On abortion, nothing the right has proposed comes anywhere near the extremity of taxpayer-funded abortions.
To govern is to enforce a brand of morality. There's no way around that.
There is a place for social conservatism, in that a healthy culture needs some norms. What norms do social liberals propose that do not equally fall prey to their own universal solvent (that social norms have no ultimately reasonable basis)?
