I was going to ask him if Xerxes ought to have just sent a million or so Persian men to demand the Greeks let them in and support them with pensions, rather than his attempt to invade by force. He could have easily bankrupted every city that way, and there would have been a large Persian population in Greece to influence things(or take over). Hospitality(xenia to you, guest right as I call it) is much abused when it is not kept within reason and custom. It is meant for travelers and friends, not groups imported wholesale. You don’t invite your enemies over(like Muslims) or just give up your land. I also had some other quotes from Aristotle and Julian himself ready. I get the impression that he has internalized Christian morality. The idea that some group of strangers matters just as much more than your own group(family, clan, tribe, people) is a product of Christian thinking. I couldn’t care less about trying to score morality points or thinking in a “modern” way. Some of that sounds just like I hear from Christians.
