I read it to mean you were claiming to be an MD as well. Maybe you have “writing comprehension” problems?

I understood it as soon as I read it, considering he was responding to someone with MD in their title, or moniker.

I understood it as soon as I read it, considering he was responding to someone with MD in their title, or moniker.

But it was grammatically incorrect, modifying the "I" of his subject, which referred to himself, not the poster with the "MD" in his name. And the person who challenged it was being ironic. Or did you miss that?
