You are one of a few authors on Medium I asked for a contribution to https://virtualagora.us/
To keep pace in a conversation, we prefer short articles focusing on one aspect of the complex issue. I suggest open borders. You can refer to my comments here. If you can relate to my three short articles on Virtual Agora, it would be great. To get the background, you may want to check my previous writing on the subject:
https://medium.com/discourse/the-border-wall-is-not-the-real-problem-40864395de58,
https://medium.com/discourse/roy-beck-the-accomplished-master-of-deception-b6f1baf1bf99,
or https://www.freedomofmigration.com/border-security-or-bs-in-brief/.
I expect that you focus on the weaknesses in my reasoning. Our objective is not to promote my point of view but to create a place where valid opinions clash in a Socratic debate.
