Generally when I write on religion, I do make that clear. If some want to dismiss my views because of that, that's their choice. I certainly dismiss a lot of what religious people say, so I can hardly call it unfair.

In a world where everyone operated as you do, I don't think there would be much point in writing, as everyone who reads what you have to say will already agree with you.

Not at all. I have plenty of good dialog with people of goodwill that I disagree with. And I have time for that because I don't waste a lot of time on people who are engaging in motivated reasoning, propaganda, suppressing cognitive dissonance, disinformation, and the like.

And I'm sure you do the same. How much time do you spend in open-minded conversation with Flat Earthers or UFO cultists or Q adherents or telemarketers? I don't think there's much point in talking with people who aren't thoughtful, sincere, and at least self-critical enough to have their acts together. But there are plenty of people who qualify.
