You can't equate "honest" and "non-religious".
Yes, I can.
In fact, I just did.
Of course: denial of the reality you can see for yourself, by yourself, with your own eyes - because it conflicts with some absurd, childish dogma somewhere - is one of the hallmarks of religious people (= liars).
No honest person can possibly be religious.
I'm religious, and I believe things that I cannot prove to be true. That is honest.
No, it isn't.
Of course nobody said a thing about "believing" or "proving" anything. Of course constructing and fighting strawmen is very much dishonest. Of course religious people have no conception of honest discourse (or honest anything).
