I think a bunch just come on here to release pent up aggression. The topic could be "chocolate or vanilla" for all intents and purposes. And I say "here" not meaning this whole board, just sections of it.

I think that any "for sale" ad is fair game for critique, because that's what's done (hopefully) before purchase. They put the picture up so you can see the attributes, determine what you like or not and buy or not. Not everbody can critique in a classy manner, heck, some can't critique in a neutral manner. But aggression never evokes respect, just fear, no matter how knowledgeable the message.
