In the 60's I lived on a dairy farm for about 3 years. (I was a foster child). The only milk we drank was raw milk. Now I've never been a fan of milk, but when I drank it, it was creamier and richer than any milk I had ever had. The milk was strained into a refrigerated stainless steel tank with a paddle that continuously stirred the milk. Don't know of any ill effects to anyone. The crap out there now is just white water in comparison. Hope this helps.
If you have a smart phone I'd load it up with facts and numbers. How the total national death count for the Covid years didn't increase over the previous years without a pandemic. Ask why more black babies are killed through abortion than any other race. Why the arctic ice pack is higher if climate change is true. All the things you think she'll go off about. Even if she continues to be an ass, at least you've showed her facts. You won't change her mind on anything, but you might make her think. Good luck fren. WWG1WGA
I was raised on a dairy farm. Trust me, it comes from both ends.
