I don't know if this counts as "hate" but flat earthers. Debunking them doesn't make you smart. Stop pretending they're relevant or scary or proof of how dumb and deluded the plebs are. On top of being a tiny, statistically insignificant minority, most of them either have legitimate mental issues or are only doing it for the meme.
People who devote time and energy to arguing against flat earth are exactly as respectable as if someone normal devoted themselves to debating people with Down's Syndrome and making "epic reckt" compilation videos of it. The Downies aren't the cows in that situation. You are.
My absolute favorite is when they can't even properly debunk the flat earthers' claims, failing to disprove the ramblings of crazy people.
I remember one video (was too long ago for me to remember the name) where they flew a camera up with a rocket or drone or whatever, and the earth under them was round. But the lens they were using made even the shot of the ground under them before the launch, look round...
You had one fucking job, man. You failed to debunk flat earth. That's like losing a debate about economics to a seven year old. You reached for the lowest hanging fruit, but were too short to get it.
One thing I've noticed, is that these proverbial midgets don't laugh at the crazy morons that they somehow manage to be dumber than. No, they get ANGRY at them. "What's this, a dumb but ultimately harmless individual posting hilariously stupid schizo shit? WHAT THE FUCK IS WRONG WITH YOU, FUCK YOU, SCUM OF THE EARTH ASSHOLE". They usually try to politicize it too, trying to paint it as right-wing or something
I don't have any explanation for this behavior, it truly baffles me. I get being mad at someone if they do something wrong, but being stupid is hardly a reason to hate an internet stranger's guts, especially when it's so fun to just laugh at them.
