The forum post you were referring to.

Sharks are smooth

Edit: 1 billion lions VS every pokemon is also up there

That was hilarious! I don't have an argument but reading through that reminded me of 2 older forum posts. A little off topic but here:

1. I put on my wizard hat and robe

2. The Bobbit Worm Chronicles

Any argument from /r/BanVideoGames is fun lol. People don't realize it's satire and it becomes the funniest part of that subreddit 😂

There was some Wikipedia article that was subject to a really long and intense conflict over whether it should have an infobox. I don't remember the details, though.

Oh my god I was going to post the same thread, but I instead highly recommend the mega64 reenactment of the bodybuilding forum fight: https://www.youtube.com/watch?v=JqylqmDl0Mw

Well, Hydrogen vs Boost obviously.

(I didn't 'read' it but it's funny)

I know it stretches the definition of Internet Argument, but this video never fails to make me laugh:

There's a reason it's called "bodybuilding" and not "brainbuilding".

The one and only Sadam vs Hitler thread

EDIT: wait, oh god, they deleted the actual thread. Tragedy I tell you!

Will have to dig up a link to it, but the Silent Hill foreskin guy is a classic.

Edit: here's an archive of some people tweeting about it.

I started reading your post 14 minutes ago and read 30 seconds every other minute then watched the video (but I didn’t count those minutes) and now I’ve grown chest hair. That was some good reppin

A little context must go into this one. For three years now, Wix has owned DeviantArt, having acquired it from its original managers. Wix then redesigned DeviantArt to have a more modern functionality, referred to as DeviantArt Eclipse. A part of this functionality is that people on DeviantArt are (supposed to be) notified whenever someone posts a work similar to their own on any website across the internet, even on the dark web, as an originality-based precaution. As a side note, I wouldn't say DeviantArt is doing the best it has ever done, but I wouldn't call it bad, but "pessimist culture" would disagree, and there are those who say the feature I mention is irreputable.

One day, a certain someone signed up for Wix and started putting art on there instead of DeviantArt. It should be noted that you can be banned from DeviantArt but not Wix. It's not usual, but I myself demonstrate this, probably because my "ban" was circumstantial and therefore intentionally made only partial (for this reason, look up my Lemmy username on DeviantArt, I'm not forgotten), but I'm only a second person here as far as Wix is concerned. Someone deep into this "pessimist culture" (I don't know what else to call it) then noticed and made a complaint accusing me of bypassing DeviantArt's detectors using their own parent website and nobody doing anything, even "with the premium service package". I kind of laughed at this, it would be like saying you committed a bank robbery by asking to speak to the manager and then asking him nicely for all the money in the bank. You kind of have to question the ownership at that point. Needless to say the fishiest thing was the accusers.

i dont have the links, the forums might not even exist anymore, but i remember a lot of d&d alignment arguments from the 00s that went on for days and garnered thousands of comments. no one changed their opinions and the comments were essay length because you HAD to (you didnt actually have to) always quote the previous post too.

good times

Years ago (early 2000s), Dilbert.com used to have a "Lazy Inventor" section of the website. "All Talk, No Funding." This was fine for a while, then someone suggested "child free days [at restaurants and stores]".

You would have thought he'd suggested clubbing baby seals. The shitstorm it generated was legendary. I'm pretty sure that was a direct contribution to them disabling that feature a few months later.

I found it in the Wayback machine! Unfortunately, it only grabbed the first few pages of comments, and the spice was only starting at that point.

One time I had to teach multiplication to Patrick Star.
