Do you understand the difference between being disappointed and let down, and being a melter? To be the latter you have to be someone who is being unreasonable, overly emotional and irrational. In other words, pissing away one's objectivity in favour of hysteria.
I think this "question my support" line is a bit disingenuous. Nobody here isn't a Spurs fan. I think the real question is whether or not we should throw our toys out of the pram after a loss as some kind of proof that it makes us a more passionate fan. We've had our best season in decades even as of today. Surely, today was frustrating, but in context it's not really justified to go off the deep end.
