Who are you arguing against here, can you show me where anyone said booing was a positive? Let's not talk pish.
You think that a crowd of 50,000 won't include folk that'll react disproportionately?
Our players signed on to play professional football in front of a demanding crowd, you don't get the rewards they get unless you are prepared to accept the responsibilities, too and right up front in responsibilities is being professional. Professional in terms of level and consistency of performance and, I'm afraid, doing that despite unfair abuse.
PS - there was a thread on here that mentioned psychos, I'm sure someone worked out that there were 1,000? psychos in Ibrox every full house. Statistically, anyway.
