Uh, yes. It's overzealous because personally disagreeing with something doesn't mean that it's outside the scope of the subject matter that the article is speaking to. If anything, you're reaffirming the commonalities between the theory and what's proposed in the article because what they have in common is a proposed difference in brain structures followed by a convergence.

The fact that you disagree with the truth of the theory has literally nothing to do with whether it's on point in response to an article that's about the same subject matter. I would have hoped that me saying multiple times that I disagreed with it would have made clear already that there's more going on here than just a matter of whether you do or don't disagree with it. Declaring that it's "not overzealous" mirrors my language back at me but without attaching an actual argument to it.
