Without watching the video, for me Patriotism was always supporting our country striving for improvements and finding pride in our accomplishments while correcting our errors.

Nationalism is just the our country is the best noone else is better and fuck anyone else. Also we never make mistakes and all we do is the beat.
A sort of extremist no thought approach to our country just because we were born here.

Patriotism requires thought nuance and a desire to build a better neighborhood so to speak.

Just my thoughts.
