You say no other unsourced things are on motivations of other human beings: "Pains are taken to maintain a certain level of mystery. This secrecy is often due to the frank—and sometimes personally uncomplimentary—discussions within the House selection committees, which are sometimes divided into factions. Also, the selection process is constrained: there are only a limited number of openings in each House, and it is impossible to simultaneouly meet the preferences of all of the Freshmen and Houses. Although typically the Houses try to make new members feel welcome as a part of the community" ... "In a defiant response to the prohibition" ... "the acronym DEI has come to be a badge of pride for Darbs" ... "This emphasis on athletics is explicitly a part of Fleming's self-conscious rejection of the nerd stereotype that developed at Caltech after the elimination of its dress code in 1968" ... "due to a play on the similarity of the name Ricketts to the disease rickets and the fact that scurvy is another vitamin deficiency disease" [EXTREMELY analogous] ... "In response to other houses quixotically claiming certain items to be off limits in regard to pranks (rendering them Non-RF-able), the Page House president at the time named that The President be unprankable as well. Not getting the joke, the Interhouse committee allowed it" ... need I continue? I haven't even gotten to the Avery section.

 The point is that this whole page is drawn from campus anecdotes and other unsourced material. As a Slave myself, I have heard this rational several times during my stays in the South Hovses. I do not see how you can call this either unverifiable speculation or some type of forum posting. WP:UNDUE is, I would argue, complete inapplicable here: the criteria given cannot apply to a large portion of this article, which is about half viewpoint at the moment. Perhaps this article should be completely overhauled to include facts only, but until that time it seems like you are simply excluding this because you haven't heard of it before, or perhaps because it doesn't appeal to you (but, I admit that speculating on your motives is pointless).

 Regarding 3RR, I can only assume that you are not the mysterious "131.215.159.106," otherwise you would be guilty of violating that rule yourself. I will be reverting the article when the 24-hour window passes. I think it might be most fair to constructively let me handle the Avery section of the article, as I live there while still having a decent amount of interaction outside the House and thus am able to gauge others' attitudes and be aware of the origins of terms such as the designation Slavery or attitudes toward Avery's changing status.
