None of this is a reason to bash BC community. It would make us look weak and focused not on our coin&project, but on the envy on others.
I think those actually bashing the BC community are a vocal minority in the Mintcoin community. I wouldn't worry too much about those types sullying the Mintcoin name - they only sully their own name. But, I agree, we should focus on Mintcoin, and not worry about winning a pissing contest with other coins.
