Not OP. Then what "value" did you even bring to this conversation then, other than to say this person has bias? Because the natural interpretation of your comment is "oh, good facts, but see he has this bias because of this word, therefore the facts must be wrong or misleading or cherry picked". That interpretation sure sounds like an ad-hominem. If there is bias, state your counter points to prove that point.

I responded to a comment that used the term "ad hominem" wrongly. A dictionary could explain proper usage of that term better than I could so I don't bother

Personally I hoped people could make strong arguments and not weaken their own stance with pettiness. It's real food. You can eat it.
