That's really gonna depend on where you live. If you live in the affluent suburbs, you're definitely going to encounter that mentality. I was raised in what is possibly the most bicycle friendly town/island in the state of South Carolina and that mentality is still very much a thing. In cities that mentality is less present, but there is the hatred of bicyclists from drivers.
The trend around Atlanta is for the affluent to just build further from the city, not to revitalize or rebuild. The middle and upper middle class seem to be the ones doing the revitalization efforts as they try to move back into the cities away from the suburbs. It's leaving this ring suburban homes form the 60s-80s around the perimeter of Atlanta that are falling into disrepair.
I've never felt this stigma in Minnesota. I had no idea it was a thing. People hate on bikers for slowing down traffic, yelling things like "get a car, loser" but I've never heard anything DUI related.
