The difference being that you are open to learning and reading more, whereas KG said that she doesn't need to learn anything else because she has made up her mind.
Nothing would ever change my mind on being pro choice either, but it doesn't stop me reading what others have to say and trying to understand their POV.
I don't think anything would ever change me being pro vax - but if evidence were to come to light that it was actually more harm than good - then of course, I would take that on board.
I don't think I just know it all, therefore I will close myself off and never listen, read or debate ever again. You know? I suspect you are the same Lamby.
