The result is that my father's tonsils were removed for no good reason after some minor infection of his during childhood, something he regretted for the rest of his life.
Here in the US they didn't wait for even a small infection. If you had three kids in your family and only one got a small infection, all the kids had to have their tonsils out. Some of the operatees regretted it later on.
I read in Back to Eden, a vegetarian guidebook with probably hundreds of diseases listed, that the disease caused by eating meat (cooked I'm sure) is tonsilitis. This book was written in about 1930. There are lots of soy and corn recipes in it.
Anyway, maybe the doctors figured if the oldest child couldn't tolerate cooked meat, then their little brothers and sisters would have similar genetics as to food tolerations. Either that or they wished they could sterilize them

. So, maybe they thought it would save time to take out tonsils all at once ahead of time, before suffering from infections in susceptible families to the disease. Several birds with one stone then, as without the tonsils, they could probably tolerate the cooked meat, and get on with eating whatever's available. You can always cook meat and put it in a can so it will last longer in the cupboard. That's where they were heading shortly after that.
My tonsils were a big reason I didn't eat meat for so long. Staying away from (cooked) meat kept tonsilitis away from me. On the few instances I was given something with traces of poultry broth, my tonsils "screamed" at me (meaning I got tonsilitis). It can be hard having to be with people of diverse diets.
