toxic fb groups

i’ve gotten some pretty mean remarks in my day posting in mom groups, but this one really took the cake today. i asked if i had a right to be upset the school had my son walk in graduation after telling me he wouldn’t be since he’s not going on into kindergarten. this “former teacher” tore me to absolute shreds, basically told me i’m a bad mom, i don’t pay attention to my kid or my kid is just slow, either way it’s 100% my fault. that if i hold him back in kindergarten he’s going to be another statistic and drop out of high school. i’ll post the screenshots in comments.
