It's actually pretty vague, since only one of your comments seem to actually acknowledge you having read the article, and none of your comments indicate it changed your opinion (one about you having the capability to be wrong, but I can't tell whether you're saying you were wrong in this case, or just a general rhetorical device).
I'm not judging you here, I'm pointing out there might be a huge disconnect between what you think you've said and what's actually coming across that would explain the reception you're getting.
That's what I'm trying to tell you, it doesn't come across as an admission, at least to me. I get what you're trying to say, but that's not the first impression it conveys
