Necromancy doesn't sound foul at all, why, summoning the spirits of the dead against their will to do ones bidding does sound rather cheerful and jovial now that I think about it.
Lemme guess, your the one guy that voted to leave it as Wizard?
a) You're implying the dead do not wish to return in the first place - And whether they would do so as a slave or not (willingly or otherwise) would depend on the intent of the necromancer and/or possibly the 'victim' in certain circumstances, if you can call it that when it comes to being dead already.
In Steveread999's case, he is referring to the old art of 'mediums', who simply wished to communicate with the dead, not force them do their bidding (outside of said communication), and on that note, if you had died and were brought back merely to impart some knowledge for the sake of your loved one(s), I'm pretty sure you wouldn't get up in arms over it compared to, say, having your corpse ripped from the ground to serve as a mindless undead meatshield in someone else's fights in the more 'fantasy' / 'magical' style of necromancy that we see in most games.
b) I honestly don't see why you'd get passive-aggressive on the guy for simply pointing old the older necromantic arts and putting a different side to the coin. It was a harmless post which some may even find interesting. Necromancy in general is written differently in every story/game.
Having said that, the 'stereotypical' fantasy necromancer, sure, your points apply.
