Regarding this subthread:
my sentiment boils down to:
Learn the language; don't be a lazy ass and whine about it.
If something's part of the language, but you're not familiar with it, that does not constitute it being "confusing".
Americans these days can't cognitively separate their perspective and the more general one. If I find something hard, then it just must be hard, right? I mean, a whole host of other people couldn't possibly have a completely different experience. That's unfathomable to today's human beings.
I've decided that I don't need to live in a big house. Therefore no one does. Therefore there's no moral problem with passing a law that forbids anyone from living in more than a 1032 sq ft abode (like mine). My experience must the universal one.
I should fucking market a line of t-shirts and baseball caps with "YMMV" with a red circle and slash over it. Because no one is capable of the concept donning on them anymore.
