I don't "actively bury" anything but I think I can answer your questions:

Why would this[2] be at only 61%?

Because it's not phrased as a celebration of other stuff, it's phrased as an insult to stuff that people like. In fact, I would say the inability for people to talk about stuff they like without going out of their way to insult shit other people like is part of the toxic culture of this sub (the same way you had to bring up a harmlessly fun topic about the J+J Security wardrobe even though it's entirely unrelated to the point you're making).

Why would this be considered off topic[3] enough to be at 0 points, with 55%?

People probably downvoted it because of the actual text of the post where he spent a hilarious amount of time boasting about a match he played in a video game was the "match of the night" on a ppv.

Why the hell would a question like this[4] be at 38% with 0 points?

I would think you would actually support downvoting this one because I'd guess that people downvoted it because it's trying to shoehorn a WWE-oriented view of wrestling into an organization where it doesn't apply (i.e. assuming there were "Eras" in WCW to begin with).

Why would decent and completely relevant content like this[5] be buried at 0 points with 54% of you downvoting it?

they shouldn't be, but people are using their downvotes to answer the implied question of whether they're willing to spend 20 minutes watching a homemade documentary about a local wrestling organization in Central City, KY

Why would this[6] be buried at 0 points and never make it past the new page?

I have never seen a wrestling results post with no content other than lists of winners and losers get upvoted, is it a common thing? It's not like WWE PPV results with no discussion / analysis routinely make the front page either
