I thought the point was to not be afraid to speak up for what you think is right no matter what popular opinion is?
Yes - but that's the point: Ronaldo has divided opinion on here from day one. It has never been a case of almost everyone
genuinely thinking that bringing him back was a brilliant idea. It may have
seemed that way right after he signed (when the thread in question was made) - but it's never actually been the case.
This place was in some kind of weird, euphoric state in the immediate aftermath of the signing: for some, this was genuine euphoria (he does have a lot of fans on here - I would never argue against that), for others...not so much: for many it was an artificial sort of euphoria, a "feck it, let's party and worry later" state of mind that lasted as long as that sort of thing usually does (i.e. not very long).
In other words, you can question exactly how popular the opinion was - and that alone means that the analogy doesn't work: the kid in the story was the sole voice of reason, pointing out an obvious truth that everyone else refused to see.
