Don't worry - nobody is under the misconception that Joz's opinion is the only one that matters. As a matter of fact, a lot of people's opinions matter... but I disagree with you that 'everyone's opinion being equally valid' - in some cases, people reveal themselves to be one who usually has an opinion that is to be discounted.
What causes people to discount others' opinions is usually when they come up with poor viewpoints that are either terrible, or ridiculous, and then proceed to repeat them again and again until they get acknowledged and validated.
At that stage, people stop caring about the opinion of that person.
If you need some examples - i'll give you three, that despite being lambasted at worst, and thoroughly debunked at best, you continue to "push":
'walkthrough dark ride monorail'
'we definitely don't need any more coasters'
'blown away'
As a matter of fact, one of the few things you've ever said on these boards that most of us can agree with is the first quote at the top!
All of this is of course my opinion, which you can't invalidate because under your system, everyones opinion is equally valid. And of course, if you choose to do so, you concede that i am correct, that some people's opinions should be discounted, in which case your opinion is less valid than some other people's... quite the paradox, is it not?
