To be honest, I think it's hard to know exactly how many people take/reference it one way or the other. Certainly there's numbers on both sides.
In terms of our general fanbase, I honestly don't know how it compares with others, as I imagine I am (like most fans, I would expect) more sensitive to and focused on what my country does. We do seem to have our fair share of pricks and cunts, though, and I don't think I've caught anyone else booing anthems (I know I go on about it, but it's just both so glaring and so petty).
It does feel, on urban at least, that for most of us it is knowing and tongue in cheek, an almost sarcastic/ironic, self-deprecating faux-bravado based on years of successive failure, often in quite dramatic/overly heartbreaking fashion. It's one thing to just go out of a tournament because a better team beat you, or because you were shite (as has happened to England many times), but it feels like we've got quite the share of 'moments' that allow people to mythologise them.
In terms of last night, though: it was the softest of soft penalties, I'm still not even convinced there was contact, and I think if you can't acknowledge that when it goes in you favour then a) you can't carp about it when it goes against you and b) you just look like a fecking idiot to everyone else on both occasions, because you're not fooling anyone.
