The answer was removed for being off topic:
The question is about the status/nature of necromantic magic in a particular fictional setting. The status/nature of necromancy in the real world is not relevant or topical; as such, this post has been removed. If you have information to provide about necromancy in the Forgotten Realms (which adds something not already covered in other answers, or which covers the same ground in a valuably novel way), you can still  this post and then flag it afterwards for mod attention and undeletion.

We get real-world adherents of religions, practices, and beliefs on occasion. The answer was describing real-world necromancy beliefs/practices, likely one of or based on one of the varieties of Vodou, and defending it as not-evil. Since that's off topic for a question about the moral/alignment status of necromantic magic in the Forgotten Realms or D&D 5e in general, it was removed.
(The beginning of the answer was at least minimally relevant to RPGs, but was off topic for the question itself: it shared that, because necromancy in D&D is unrealistic, they like to give players the option of playing a more realistic homebrew class. That's not topical to the alignment status of necromancy in the Forgotten Realms.)
The speed of the deletion was just a combination of seeing it shortly after it was posted, and familiarity with this sort of post making for easy recognition and diagnosis.
