Mind is the brain?

The author wasn't arguing that we should accept dualism. He wasn't arguing even that materialism shouldn't believed in. He was simply saying the arguments against dualism are all fallacious and baseless.

As I said, he is an Atheist, and he use to rely on some of the fallacious arguments.

Well, he might be attempting to argue that, but all he's really done is shown that those arguments aren't perfect, airtight proof against dualism, which... I mean... yeah. All evidence-based conclusions are probabilistic, but the fact is that A: an evidence-based conclusion would not lead to dualism and B: not having airtight proof against a position doesn't mean that position is on equal standing with an evidence-based conclusion. The fact that there are ways in which a dualist could wriggle to escape the arguments against dualism is trivial and irrelevant: finding a loophole such that your position still might be possible just puts you back at zero evidence and zero justification for that position, it doesn't mean that the argument you've wriggled out of is totally useless, or fallacious.

It just means that people with prior commitments to positions can find ways around contradictory arguments. That's nothing special.
