True patriotism is similar to love for your parents.
You appreciate and acknowledge the traditions and culture of how they raised you. You understand that they aren't perfect, and accept their shortcomings. You are proud to tell people that they are your parents, and share stories of what they have done for you. And you do what you can to protect them if they are in danger or need help.
And false patriotism is a lot like false love for your parents.
Reluctantly obeying your parents out of fear, is not love. Being lied to and manipulated by your parents to trick you into loving them, is not real love.
If you truly loved your parents, and they were making destructive choices, you wouldn't stand by, say "I love them, so they must know best!" and watch them destroy themselves. You would take action to get them help and get them back on track.
