Nationalists don't really care about the rights and freedoms of other people. They are only concerned about the rights and freedoms of their own country.
Someone's political ideology is their political ideology, you might think it makes sense given the context but (for example) socialist economic policies don't become less socialist by being popular or making more sense or less sense in the economic context.
You might think that Abe's positions are correct or the norm, I don't believe that changes the judgement that he's a pretty heavy nationalist. Nationalists are willing to torpedo economic relationships with neighboring nations out of national pride. Loads of people are not nationalists!
