I don't know if GP meant civilization was a dirty word, just that it's an overloaded term, because it at least partially means, "ordered society" and partly it means "society ordered like ours". In this context, taking it to mean the second meaning could be incredibly arrogant, so I think it's reasonable to be careful about one's meaning.
