He's estabishing certain premises with which I might or might not agree.
I personally think people are a combination of individual and social elements. Very few of us could survive on our own. We depend on each other for not only material substenance, but also emotional, psychological, and 'spiritual' support.
BUT we also need solitude, freedom, and autonomy.

So to artificially say we're PRIMARILY one or the other is a fallacy.

"Hey, you want me to be a Nazi or you'll kill me? No problem!" OR "You want me to be an anti-war peacenik or you'll make me go to Vietnam? I can do that!"
The extent to which we will mold our thoughts to whatever stance is most convenient at the moment, is limitless.
So nationalist or rugged individualist, hey, whatever works!
AND, it goes without saying there's plenty of 'nationalist liberals' and 'individualist conservatives' running around, to say nothing of 'individualist liberals' and 'nationalist conservatives...' maybe more!
(Hey, if someone can call themselves an 'agnostic theist' or a 'atheistic agnostic' they can call themselves anything.)
