Why would the 5 or so disagree so harshly about something factual. How come only they in the universe have the secret knowledge that is unattainable for others

Reading comprehension and organized harassment is such a problem for your community that the entire rest of the fediverse knows and jokes about it. I can appreciate that you might not see most of that because most instances defederate from yours and most users block you after the first interaction.

It's totally normal and organic that entire groups of tankies show up at the same time to dunk on low-interaction comments in low-interaction posts, often several replies deep in a thread that nobody's reading anymore, and it's always the most meaningless shit where they clearly didn't read the post and formed a cohesive rebuttal to any points but just spew the first vaguely relevant zinger they find in the text file of one-line zingers they seem to share amongst each other.
