It does exist, and taustin made one,
No he did not.
And no: there is nothing like an ad hominem attack . I is simply called an 'ad hominem', and that is a fallacy, and not an attack.
And "wording" is not aimed at the person you are talking to.
And ad hominem goes like this:
Trumpster: "we have to make America great again" (actually not a bad idea, but he does not achieve it)
Angelo: who would follow (vote for) an convicted rapist? Let me make America great again!
The "ad hominem" (it is literally in the name of the fallacy) is: I discredit the person - and I am right with my point - but do not address not what he said.
Ad hominem(s) usually do not happen in talks were two people exchange arguments, they happen when you talk about someone else, who's points you like to weaken.
