Thats YOUR belief.
This tent (Christian and Republican/Conservative) include people with VERY different beliefs.
I do not beleive that what he said means that he is calling God a liar, and neither does my entire culture, society and ancestry going back over a millenium. You may believe that, but you have to accept that you need to deal with people (and there are many, many millions like me) who think you are very mistaken.
I don’t think we disagree on our core principal beliefs. I would probably agree with you 95% on conservative ideals. But denying that the Bible is not true in all parts is opening up the entire Christian belief system to question. That’s a camels nose under the tent for non believers to ridicule and question Christianity and its entire moral foundation.
