Why can't nationalists discuss the definition of nationalism?

The people who call themselves nationalists but cannot define nationalism and refuse to discuss it with me are fraudulent atheists claiming to be capable of rational political discourse when they just hate and blame certain religious groups. They resent Jews and Muslims for enjoying a higher status to them because they have the protective wrapper of their religion. The fact that these so-called nationalists are atheists and Jews and Muslims are treated better than they are by their government have a religion should be enough of a clue as to where they have gone wrong, but they are too intellectually dishonest to discuss this, let alone admit this.
