Yes, I have a problem with the editor you've mentioned (and judging by its talk page, I'm not the only one). He/she seems hellbent on deleting as much material as possible without any just explanation; wherever, whenever. When my other contributions have been modified by other editors, I've willingly accepted it and even thanked them for their explanation (go ahead and check if you want). Perhaps your issues should be with the editor you're defending and not me? Think about it.
