Aren't Black mages suppose to be void mages?

They tend to combat voidsent whenever possible. Sorta seems counter productive to attack the very thing one draws power from, so I don't think they are void mages. They do love raw power, however. I could be wrong too, and would certainly welcome some clarification. Been a little while since I did the BLM quests.
