Well I personally disagree with that. I use the Amiga for playing Games and nothing much else (apart from DPaint) and I've had plenty of problems along the way. I feel an Amiga board should allow people to express both negative and positive views on the current state of the Amiga.
I personally have no interest in new Amigas, I don't think they offer anything 'Amiga' at all, and I'm entitled to that opinion. I feel I should be able to post that opinion here.
Granted some recent posts have gone too far, but an outright ban on Amiga negativity is a stupid idea.
