There is a LOT of this type of sniping going on FB … and for a while now, as the energies work on people who “think” with their mouths. Bottom line:  Don’t buy into the hype, no matter how ugly the language spewed at you.  It’s best to ignore misnomers, and if they happen to be people, all the better.

Ad hominem: Attacking your opponent’s character or personal traits instead of engaging with their argument. Ad hominem attacks can take the form of overtly attacking somebody, or more subtly casting doubt on their character. The result of an ad hom attack can be to undermine someone without actually having to engage with their argument.
