I think the article is pretty fair at presenting GingerBill's legitimate grievances, Wikipedia shortcomings, acknowledging that GingerBill can be constructive and, at the same time, recognizing that the current interactions are coloured by his particular ideological grievances.
It is only at the end of a very long, well-argued article that he is very critical of GingerBill's positions. I don't think I agree that calling someone out on their contradictions or political opinions constitute "stalking".
