Patriotism is fine.
Nationalism is weird.
Thanks to a general knowledge confusion over the two, I haven’t worn a US flag pin on me since the 1980s.
It sucks too but too many folks don’t know the difference and include me in stuff I don’t want to be included in, or say “You’re not a real [x] if you don’t [x]” crap.
So I just keep it to myself mostly.
But, I became President of Earth on Earth Day, 2015 so it’s ok.
Google President Udut.
