To even think of defending the FACT there is nothing wrong with nationalism and love of ones own peoples (something which is as natural as breathing), is to admit disbelief.
The OP is premised off the uncertainty of the good or Christian-like nature of ethno-nationalism. Nothing wrong with me telling her it's not wrong and why it's not wrong.
I think you do not really believe what you are saying. If you really believed that you were right, you would not debate with anyone that was against nationalism and love of ones people.
I think you're constructing a make-believe narrative to compensate for something you lack. Whatever it might be...
I would say "neat story", but I can't because it's not...
When you debate someone, you also empower them. You are empowering your enemies.
Oh, so I guess St. Augustine, St. John Chrysostom, St. Thomas Aquinas, et al, empowered their enemies. Thanks for letting me know that debating is bad and I should become a eunuch.
