Seriously, that exact same scenario in Call the Midwife.
Anyway, the point is that blacks are at a lot higher risk of drowning. There's no doubt that whites drown as well..just not at the same rate. Because we promote swim lessons amongst our poor people.
My incredulity isn't based on my thinking that white kids don't drown... my incredulity is that there are morons who don't think black parents should be told to teach their kids to swim.
I do enjoy "Midwife" but didn't see the episode you noted. Anyway, your point is a valid one though stupidity is not exclusive to any one race or ethnic group. BTW, PM and VM wouldn't work.
In the instance from my younger years - and things are popping back to memory which hadn't in many decades - this was a case of a mother (who happened to be white) keeping her kids away from what I might call "socializing" activity. I think it was a class-related thing. First off, there wasn't anything in the way of racial tension in that small town. There was only one black family and they were well regarded, having developed a business raising turkeys. Their one son died just a week ago, still in the old home town, leaving several grand and great-grand children, all of whom are doing very well.
The non-swim issue seemed related to the fact that the women who ran the free swimming lessons program were of a different economic class. Not wealthy; just having time to devote, suggesting (as was traditional) that they didn't work outside the home. That relatively small economic difference translated into something cultural that kept the particular woman's children from having a lot of opportunity they might have had.
You got me thinking about their father - her husband. No "single mom" situation. He was a physically small, mousy individual - not a drunk or layabout. He worked in a manufacturing job that paid decently but he never advanced, always stayed at the bottom of the ladder. Did he have the ability? Dunno. He was what he was - she dominated.
So how much of the swim/no-swim is not actual stupidity, rather some kind of class or cultural thing?
On another extreme, I have done a little work (not recent) with a northern ethnic group which until recently would not allow anyone to learn to swim. Their logic was that given how they subsisted they had a strong chance of finding themselves in extremely cold water with nobody else around to help. So to swim was to deny themselves a quick death. Not putting you on - it was something that had to be overcome because the overall situation had changed but a whole lot of folks were unwilling to accept that.
