When did "we" lose the ability to detect sarcasm? [View all]

Especially really, really obvious sarcasm:

The context is five years ago, when the NY Times was putting in their much-maligned internet paywall and the internet went nuts. The tweeter is Neera Tanden, now a Clinton appointee to the platform committee.

To me, it's obviously a sarcastic joke and a poke at the NYT, and yet, nearly the entire thread full of Sanders supporters is taking it completely literally. So, I guess she's for an individual mandate *and* thinks everyone's a freeloader. Uh, huh.

Sarcasm is basically my default emotion, so maybe it just seems obvious to me. Thoughts?
