It's widely used in politics, most famously by Rahm Emanuel in 2008, but I have seen it in other contexts as well. The Winston Churchill attribution seems false though. If you think those guys are "ridiculous" and unserious, then ok, you do you. I'm aware of that medical usage, though if you think it's the only relevant one you're not using google very well. Not being able to generalise seems to be your thing.
