You kinda have to put it together, but the other author comes across to me as disingenuous and dismissive. Look at the edit log and the talk page together.
Wikipedian, 4/19: Deletes one new section of the article that he disagrees with. Entire comment is: " (-1,214) . . (→Typhoid Mary: not a super-spreader. she was an asymptomatic carrier; super-spreaders are symptomatic)"
Student: 4/19: "There was dispute about whether or not asymptomatic carriers could be considered super-spreaders." Defends her position with un-Wikipedia-esque speech, reverts deletion.
Wikepedian: 4/20 Deletes every single thing the student contributed. (This is where things go off the rails.)
Wikipedian: "Also, I'm not aware of any "dispute as to whether or not asymptomatic carriers should be considered super-spreaders", so perhaps you could also provide a source for that."
The source of the dispute is that he reverted her edit; of course it exists.
The student then comes back with a source to defend that Typhoid Mary is considered a super carrier by serious sources, and gets no response.
Further, if you look at what the editor excised, it was a sincere edit, well-sourced, and deserved at least a modicum of respect for trying to help his pet project.
