Me? I dunno. In my lifetime (46 yrs old now), Nationalism was “America Right or Wrong” bumper stickers while Patriotism is being proud of America when America is doing good and disappointed in America when it falls short of its promise as an ideal.
So, I don’t care if Nationalism gets a good name or not: it never had one for me.
Patriotism has always been the realm for me. Nationalism was always a weird extremism to me.
