No, I think they disagree. Or at least, I don't mind treating them as such.

From sudoer:

Basically what they are saying is just praying > praying + smoking > just smoking.

This is the basis of the entire argument. What I see them doing is hyperfixating on an alleged flaw as a rhetorical tactic to defeat you.

I want to be clear: the point being made by the A and B versions of the smoker's question is... obvious. It's framing. Framing is a very well understood concept.

When I challenge people on grounds like these, I appear friendly, I make it explicitly known that I agree with the broader point, I offer alternatives that would make the point better, I refrain from damaging the rhetorical momentum (that is, we shouldn't be bickering with each other because, to an audience, we should be a united front), and, I dunno, a fifth thing I'm sure I'll come up with later.

If sudoer doesn't disagree with you, they are still acting in opposition to you, which is 1) inconsiderate, and 2) demonstrates very poor social skills.
