You can prove that your OP was not aware of the existence of the aquaduct? And what is the purpose of pointing this out? "I was stating facts" seems a flimsy defense. Do you thus claim that the statement of facts is morally acceptable, in all circumstances, at all times? I hope you'd find this suggestion as absurd as I do - imagine walking up to someone at a funeral and saying, "in two months your mother will be wormfood." Facts? Yes. Necessary? I wonder.
