I think a lot of the rhetoric surrounding the earlier Prohibition movement (leading to the 18th amendment) was about immigrant men getting drunk in saloons.
Possibly, but I do know that since at least the 80s you could guess the nationality of the most public wildest and totally out of control drunk driving violators in the newspaper articles as being Hispanic, and you would be correct in the majority of cases.
My real point though is MADD and their excesses, they didn’t go after the crazy wild drunk drivers, the fought for zero alcohol, first .8, then .5, and whatever they could get.
The loss in socializing and community and people having fun with each other, making friends, and building relationships may not have been worth the cost.
