We can talk about religion all you like. Nothing will make me doubt. Nothing you say, nothing you do, nothing anyone says or does will make me doubt that God is real and that He loves me.
That's the definition of closed-mindedness, and it's characteristic of faith-based thought.
Here are several examples of religious people telling you that their minds are shut off to evidence (closed):
[1] The moderator in the debate between Ken Ham and Bill Nye on whether creationism is a viable scientific pursuit asked, “What would change your minds?” Scientist Bill Nye answered, “Evidence.” Young Earth Creationist Ken Ham answered, “Nothing. I'm a Christian.” Elsewhere, Ham stated, “By definition, no apparent, perceived or claimed evidence in any field, including history and chronology, can be valid if it contradicts the scriptural record."
[2] "The way in which I know Christianity is true is first and foremost on the basis of the witness of the Holy Spirit in my heart. And this gives me a self-authenticating means of knowing Christianity is true wholly apart from the evidence. And therefore, even if in some historically contingent circumstances the evidence that I have available to me should turn against Christianity, I do not think that this controverts the witness of the Holy Spirit. In such a situation, I should regard that as simply a result of the contingent circumstances that I'm in, and that if I were to pursue this with due diligence and with time, I would discover that the evidence, if in fact I could get the correct picture, would support exactly what the witness of the Holy Spirit tells me. So I think that's very important to get the relationship between faith and reason right..." - William Lane Craig
[3] “If somewhere in the Bible I were to find a passage that said 2 + 2 = 5, I wouldn't question what I am reading in the Bible. I would believe it, accept it as true, and do my best to work it out and understand it."- Pastor Peter laRuffa
[4] “When science and the Bible differ, science has obviously misinterpreted its data. The only Bible-honoring conclusion is, of course, that Genesis 1-11 is actual historical truth, regardless of any scientific or chronological problems thereby entailed.” – creationist Henry Morris
None of these people can correct errors that they have made even when there is evidence to confirm that, because the evidence can't enter their minds, which are closed for business in these areas.
Here's what open-mindedness looks like in addition to Nye's comment above:
“The difference between my beliefs and having a religious faith is that I am prepared to change my views in light of new evidence, but someone of a religious faith will just stick their fingers in the ears and say: 'I'm not listening, there's nothing you can say that will make me change my mind.” - anon
Isn't that your position? It's Ham's, Craig's, laRuffa's, and Morris' They were quite clear that nothing can change their minds - proud of it even, like it was a virtue. 'Our minds are sealed':
It doesn't matter what they say
No one's listening anyway
Our [minds] are sealed
You are assuming that I will always believe a certain way. That's the part that's wrong.
He's assuming that you know your own mind, and that when you say it is closed (you didn't used that word, but you described it perfectly), that you mean it.
