You're not wrong about people resenting being talked down to. I've tried to make this point to Democratic (especially progressive) activists for years and years and it's like talking to a dog that just heard a new noise. The fraction of people in the country that actually care about religious culture wars is relatively small; it's one reason why seven states passed initiatives enshrining abortion rights in their state constitutions this go-round. Voters care deeply about concrete things that affect their lives and they're not receptive to someone haranguing them to care about something else entirely.

If you want to catch a fish, you bait the hook with something the fish wants to eat instead of something you want the fish to eat.
