I don't understand - running is individual and personal to everyone, what does it matter if they're 'lycra-clad' with iPods and biceps? I understand your frustration at being a 'serious runner' and finding that some people just don't take it serious enough (believe me, I've been there too) but at the end of the day, if people are participating in running and getting enjoyment from running, surely we should get off our high horses and welcome them into the sport that we all love?
