No, it isn’t reasonable.
If rationalfrummie wants to come with a cut-and-dry claim that God does not want women to study Gemara b’iyun, that’s one thing. But he didn’t say that. He directly implied that the satisfaction derived from learning Nach and Halacha is the same as from learning Gemara b’iyun and that therefore women shouldn’t complain. That is a disingenuous claim, and it makes a joke of a serious issue.
