I don't think that makes his point invalid, if based on statistical evidence from wiki (lol) 2/3 of the time Necro is a enemy job. Just because you say it isn't does not change that fact. Even if you're summoning undead for good purposes in XIV how does it distinguish itself from a summoner? I get it would summon undead not primals, but after that there is little distinction. It's an undead summoner.

edit: grammar
