I believe kirottu was trying to make a point that you were talking nonsense by using an appeal to ridicule. (An example wiki gives of this type of argument: If Einstein's theory of relativity is right, that would mean that when I drive my car it gets shorter and heavier the faster I go. That's crazy!)
You suggested there would be little difference between a post-apololyptic Europe and America, as both would be focused on reginal conflicts, and a great deal of what makes European culture European would be gone.
He ridiculed your statement using this logic: If Jorian Drake's argument is correct, then we might as well disregard the pretence of a post-apocolypic Europe resembling our world at all, and instead portray it as a land filled with Elves and crime lord Huts who take counsel from Jedis, Mages and Druids.
Um... I thought Morgoth
