Ah, I see your confusion. Advocating for the dismissal of her opinion on grounds of her profession is not a slight on her character. I’m sure she’s a very nice girl and a talented musician.
You see, ad hominem is an attack on someone’s character to distract from the lack of merit in one’s argument. I never slighted her as a person, ergo no ad hominem.
Now if I said she was stupid or ugly or talentless, therefore no one should listen to her, that would constitute an attack on her.
I hope this clears things up.
Let yourself be cold for a bit, too. If you immediately try to fight off the cold, you’re not letting your body acclimate. There’s only so many layers you can throw on, but if you allow your body to adjust, there’s less layers required.
