Have you ever noticed how God always agrees with you? Not as often with your neighbor, your congressman, your family or even the pope. But he (or she, or it,) definitely agrees with you. Other people just aren’t enlightened enough to realize that. Yet.
Funny how that works.
Was the Christian God cool with slavery? Slave owners sure thought so — and had plenty of Biblical canon to support it. Abolitionists disagreed. Did God want women to vote? Not according to anti-suffragists. Suffragists were convinced otherwise. If society continues this descent into level-headed compassion, fifty years from now people will be claiming that God is pro-fur and factory farming. When one cannot defend a belief in the current context, moving the framework back a few thousand years and putting the blame on God is a pretty good fallback strategy.
Long examination of how the faithful cherry-pick their holy book to justify their prejudices. Obvious, but needs to be said, and said again.
