Born and raised Michigander checking in. There's a LOT of cultural variation in the Midwest that people gloss over. You can find extremely liberal population centers all around the region. Chicago, Detroit, Ann Arbor, Madison, Lansing, Milwaukee, etc
Same in Oregon. Never seen a "don't rape your children" bilboard or "don't shake a baby" bilboard. I do however see a lot of bilboards telling me how a 14 day conceived baby (fetus) has eyes, a beating heart, nails, and maybe a job with current labor laws being pushed. It's wild how you can outright lie about that shit on a bilboard.
I technically live in southern Illinois near St Louis and I've not seen incest sounds only intent ass anti abortion signs. None of which mention when a fetus becomes self aware.
I actually haven't but I only leave the city after work. The most I've seen is churches blaming the pandemic and the climate on lack of faith. I try hard not to look at billboards die to how frustrating they can be.
Growing up in Wisconsin, drunk driving was a serious issue. Especially on New Years and the Fourth of July. The joke was that every little town throughout Wisconsin always had a church and a bar. There were so many alcoholics that would spend every day at those bars. It's a tradition that probably goes back to the idea of public houses and having bars be a central location where your community gathers. Many people take the drinking part of that too far though and so the anti-drunk driving PSAs were necessary.
