I used to think it didn’t make sense to argue about religion, because it was impossible to convince anybody and, perhaps more importantly, disrespectful to try.
After all, religion is about someone’s relationship to his or her own soul and to matters of ultimate concern (G-d, the Tao, the Dharmakaya and such like) and those are the most deep and intimate issues, and nobody else’s business.
But I just read the Washington Post article about evangelical support for Trump, and it seems like the only way to engage is to talk about religion. For example they think everyone is a sinner and it’s self-righteous of progressives to criticize Trump. They think that science is opposed to religion and the only way to avoid thinking that life is a meaningless joke is to endorse a fundamentalist reading of the Bible. It seems like the only way to argue with these ideas is to get in a religious argument about the true meaning of the Bible, who/what G-d is and how we should think about Him, sin, mitzvot, the purpose of life etc.
And yet I think my first point is valid too — it’s disrespectful and a waste of time to argue about religion! People have a bad track record of answering these questions, and it is obnoxious to expect people to agree on them.
It’s a puzzler.
