An large percentage of the regulars (as in it's mildly larger than the general population) are autists, troons, or both. At least three of the mods are troons. And TVT has never been openly right-leaning site ever since Fast Eddie got rid of anything that remotely mocked CWC and praised Something Awful and Encyclopedia Dramatica because "it was attracting trolls." He also permalocked the 4chan page on a era when that imageboard was losing it's relevance.
After that, that was essentially it until we get shit like them chimping out over The Snoot Game, Victoria, and Stonetoss because they can't process political satire without "promoting hatred" if it's coming from the right.
Personally, it's just the decline of modern society and that wiki's history is just reflecting it.
