I believe it’s a big reason behind them.
Following repeal, some states continued Prohibition within their own jurisdictions. Almost two-thirds of the states adopted some form of local option which enabled residents in political subdivisions to vote for or against local Prohibition. For a time, 38 percent of Americans lived in areas with Prohibition. By 1966, however, all states had repealed their statewide Prohibition laws, with Mississippi the last state to do so.
Well, Mississippi is a religious state, no doubt. But I’m guessing it was real tough on morality – for the sake of the Black residents, not the White. Probably it’s expected some Whites would disobey, but they (the lawmakers) don’t care. In fact, as with pot laws, it’s all about controlling what are seen as dangerous populations. In fact, Prohibition itself was mostly motivated, probably, by Fox News types (of that era) concerned over those “darn immigrants” lol.
Another Insane Thing
South Africa literally banned TV until the mid-’70s, much later than the early ’50’s when TV became popular in the English speaking nations generally, and only because they feared chaos if Blacks saw White women on TV.
Feminists or Proto-Feminists Behind Moral Laws
@Robert Lindsay advocates this but I seriously believe the strongest force is racism.
