This isn't really a new concept. Someone reminded me that, back before my time, there were "chicken pox parties," so that people would just get it en masse, get over it and have the immunity.
Of course, the people who are doing it now are just morons. They're having Corona parties, and... they're not going to build an immunity to it, that's fucking ridiculous. It's not the same thing. They're just increasing the potential of spreading it to each other and everyone they and their 20, equally stupid people, come into contact with over the next couple of weeks.
The beach thing, the corona parties... it makes me so angry.
