Yes, you are. It isn't solely about making predictions yourself, but also which side of an argument you support and defend.
When you do something like you are doing in this thread - portraying the people who think that Switch will sell very well as a ridiculous mob - then you become guilty by association. You don't have a neutral stance on this matter, hence why you portray the doubters as reasonable and the opposition as unreasonable. You explicitly state that this thread is an example of the behavior that you see, but here the main point of contention is not "Will Switch sell 100m+?" like you say, it's "Will Switch's year 2 be better than its year 1?" - And you portray the people who say that successful consoles don't peak in year 1 as rabid, even though all historic sales records show that consoles with a healthy first year like Switch do not peak in year 1.
You have absolutely missed the point. I also think the Switch will sell better in 2018 than in 2017. My post was about the fervor with which positions are being defended, and the hostility shown to those who disagree. Or even in some cases, those who don't agree strongly enough.
Your condescending tone, and your constant attempts to discredit people who disagree with you as bias while having seemingly no self awareness about your own bias makes you a perfect example of what I was talking about.
Bet with Adamblaziken:
I bet that on launch the Nintendo Switch will have no built in in-game voice chat. He bets that it will. The winner gets six months of avatar control over the other user.
