I'm sort of wondering what glass "should" look like anyway. I always thought it should be pretty transparent, otherwise you'd be as well using wood. I can't say I've ever really paid much attention to what glass looks like.
As for the rest of the argument, I don't care. If you want to shout abuse at each other, please create a new thread or, even better, a new forum where such a thread won't get you banned and I don't have to look at it. I'd love to ignore forum mongs, but the problem is you end up only catching the odd comment about it and that's even worse. Shutting up and actually physically ignoring them is much better.
Of course the mature thing to do is not respond, but you can't have anyone have the last word on the innertubes, can you? The last word makes your penis bigger.
