thanks...to me i tend to think of Mel Gibson in "the patriot" and "braveheart"
A patriot is loyal to the country as a demographic entity. A nationalist is loyal to the nation as a political entity. One may then ask, what's the difference between a county and a nation? Let's not go far as one example that's close to us would be the merger and demerger with Malaysia. In merger, Malaysia was our nation; in independence, Singapore is our nation. A Malaysian nationalist in Singapore then might feel betrayed by the events whereas a Singapore patriot might think it it's better that way. Different motivations, but both in good faith.
