I think part of being well-reasoned is being honest, and they're certainly being honest. I don't agree with their means, though. Bill is a complex person, and you don't have to stalk him to learn about him. He interacts with newbies plenty in the Discord server. I find him to be pretty nice in those interactions.
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".
