Dear Christian Nationalist,
To say "If you don't like it, then leave!" is not only exclusionary, but, with all due respect, it's narrow-minded. At least it makes you sound narrow-minded. Remember, you and people who agree with you don't own the market on patriotism. I'm confident that you understand it's possible for someone to not agree with you and yet still be patriotic. And to still love our country. And to still fight for it. Don't get caught in the trap where your first reaction to an idea or a stance that you disagree with is that it's anti-American.
Sincerely,
Andy
