Very interesting thread. I don't have much to add at the moment but I want to make a couple of comments:
1 - i seem to remember that there might be some relevant material in Diskin clay's article "Epicurus' Last Will and Testament"
2 - As this thread proceeds, please everyone be sure to keep the commentary general and not take argumentative positions on current-day issues of immigration / migration. Those are extremely important and even critical issues for everyone in modern life. I urge everyone to pay attention to those issues and take positions and relevant actions in their personal lives. There is going to be strong disagreement, however, on what those positions should be, and this forum is not the place to argue such positions.
3 - Another quote to factor into the mix would be what Diogenes Laertius records here as to what Epicurus said about the Cynics in the list of Epicurus' statements about other philosophers: "...Democritus Lerocritus (‘judge of nonsense’), Antidorus he called Sannidorus (‘Maniac’), the Cynics ‘Enemies of Hellas,’ the Logicians ‘The destroyers,’ and Pyrrho ‘The uneducated fool.’"
