I left /c/Risa because the moderator there was letting his own personal feelings color rules, removing posts that violated no clearly written rules, and creating new rules without even running it past the community or asking how they feel about it.
The moderator of this community is guilty of that same behavior.
I'll be over on !whitepeopletwitter@sh.itjust.works.
Almost the same. 3rd grade (8) for me with mom - she forced me to turn in homework that proclaimed 3x0=3, it went downhill after that day. For my dad, somewhere around 12 - the man was a wizard with fractions and conversions for structural load-bearing which was part of his job. My 7th grade advanced math course taught me the tricks and I realized it was actually easy, backed by experience.
Honest, this broke me too. It triggered the deep fear that things my parents tell me are factually true, might not be. I made it a point to check and verify every “fact” including education, religion, even local history. Shit, while helping my ex-wife do her family history (for jure sanguini), I checked into mine and found absurdly erroneous family links and claims (all “proven”) of wealth, royalty and castles - wrong. I will never correct my dad on this, but it’s sad to hear him repeatedly tell these stories, it would crush the only thing left he finds worth living. He’ll pass in a year or so, let him live his dreams.
