What's the longest internet argument you have had?

I had an argument that went on for 8 months in a YouTube comment section. At the start I just left a comment on a ww2 documentary i was watching trolling by saying that I didn't believe ww2 was real became there was no proof. The argument shifted across many topics since there was now 10+ people arguing about random things. I think we covered the moon landing, communism, the justification of dropping nukes on Japan. I just made up random things and baselessly attacked the validity of the claims others made.

I think the youtuber ended up deleting the thread because it just disappeared. None of my other bait posts have ever started that much of a shitshow and its disappointing.
