I will say this. I don't think Dom's comments were constructive. I would have much preferred he give countering arguments and sources instead of just basically saying "you're wrong" and leaving it at that. Posts like that either show that you have no argument or that you're lazy. Which was it?
I will also say that I would not have shut the thread down if it were up to me. You'll have to ask the MOD where he/she saw politics
