GOP has to reconcile keeping people free from government and wanting government into social policies.
Not hard to reconcile. We don't want government to do anything more than what the founding fathers intended. They declared we have the right to life, liberty, etc., so we cannot allow abortion.
As for marriage, the government isn't getting involved in anything by not allowing same-sex marriage. They are staying totally out of same-sex relationships by not allowing same-sex marriage. Anyone can get married in a church of their choice. Doesn't mean the government has to provide benefits for it.
