I think the disapproving of thinking may well come from having got fed up, many years ago, of being berated for not thinking enough. I've been wondering all day about the parallel with recreational running, which is the same kind of doing things well for fun which other people don't want to be involved in, and I think the difference is that while runners may be in-your-face and enthusiastic and fitter than you they tend not to be proselytising and dismissive (and paid for it). But if your pub was taken over by people ostentatiously doing press-ups you might think about going somewhere else.

Sigh. (Intrusive video game going on in background.) I'm still in favour of thinking, I just can't do it tonight 8-(
