It is not an ad-hominem, ad-hominem is a personal attack on your character, ignoring the argument. All of those things the parent posted are accurately used to discredit your argument. Saying "you have bad hair therefore your argument is bad" is ad-hominem. Saying "This person has never worked a 9-6 office job while supporting 2 kids, a stay-at-home-partner and a mortgage; therefore they are unqualified to make such statements on how adults should spend their time" is a completely legitimate argument to make, it is not a personal attack.
