I failed a science class (biology?) because I refused to write the 3 hours worth of vocabulary homework we were assigned every night. Hand writing vocabulary, out of the book, just because. Never had any bearing on how well I did on other assignments, but the homework was a large part of the overall grade, and for some reason NOT actually knowing the material.
Its engagement bait, trying to make you click through and argue with people. I just hide/snooze it all as it shows up.
