When you're having a conversation with someone who is closed-minded, keep in mind that you should not push further for them to understand your point of view and attack them for being wrong.
As long as we keep refuting their point of view it will only make them see it as an attack and prepare more alternatives for rebuttal.
"I no longer believe it’s my place to change anyone’s mind. All I can do is try to understand their thinking and ask if they’re open to some rethinking. The rest is up to them."
