 While you are correct to reject unsourced or primary-source-only material about a living person, as WP:BLP requires, you might also want to take a bit gentler tack than calling the edits vandalism—I don't see any vandalism there, I more see newer editors who really do want to contribute and aren't aware of sourcing requirements and such. It appears the existence of the column itself is quite real; perhaps you could work with the other editors involved in looking for appropriate secondary sources on the controversy, rather than simply reverts as "vandalism"? I really don't think semi-protection is required right now.
