laughter = "i am right"
libs were brainwashed by this from late night tv show hosts like colbert for years
colbert: i'm retarded as fuck. oh wait *laughtrack*
audience: wtf he's right somehow!
it's cuz when you hear the laughtrack on a late night lib brainwashing show, the laughtrack is at "the enemy" so if you don't get it/aren't laughing then the laughtrack is at you, and that's bad. if you laugh too then you're on the side of the good guys, or the laugh track, so no one's laughing at you, and that's good.
you often see libs who are cornered in arguments type HAHAHAHAHAH or LMFAO or use laughing emojis in a desperate attempt to emulate this effect, but it doesn't work unless u are also a brainwashed lib.
