In all honesty, his claims have no foundation at all. Even the most devout Christian, assuming he identifies with Christianity, will acknowledge that any references of that kind need to be read in context.
Think about it. There was a time when the laws of your society said that women couldn't vote. Those laws are irrelevant now but their existance is a matter of fact. So, someone comes along and points out those laws, refusing to acknowledge the later injunctions which overturned them.
But sadly, there are politically ambitious people who seek to manipulate others.
I suggest, with respect, you try to avoid these confrontations. You and I both know that there is absolutely nothing to be gained. Your father will never listen to you.
As a sort of comparisom, when I use to work in elderly care homes, many years ago, there would be occasional residents who would rant on about Germans, Communists, blacks, Scots, you name it. I was once chased by a man who was convinced I was Irish!. We weren't permitted to humour people. That has been unacceptable in care of the elderly for many years. So we just had to stand there and accpt that that is how they are.
I really hope you don't mind me saying this. I know how frustrating it is. My own family got so bad I cut off all contact with them, one by one, the last being about 15 years ago. But if you need to continue contact with your father, I suggest you just rise above it.
He's wrong. But you are never going to convince him of that.
