You might want to re-read the conversation sometime when you’re in a generous mood. From my outsider perspective, the comment you are replying to is entirely reasonable and not personal (“The major complaint from parents [..] seems to be” is not the same as “your complaint right here”), and then you flew off the handle and started cursing the commenter and your son’s teacher in all caps. P.S. this “If we want to actually fix elementary math education, that would be simple.” is a pretty ridiculous statement, unless by “simple” you mean something like, «Create a new job for elementary school math teachers; hire well qualified candidates; give them rigorous teacher training; pay them much better, provide a longer career ladder, give them more autonomy, and show them dramatically more respect than currently; and reorganize the whole school day to give the new math teachers time for introspection, collaboration, and professional development. While we’re at it, fix and improve school facilities, and make sure every school/teacher has the resources they need.» In that case, sure, “simple”. (Note that the specific curriculum used has little to do with any of this.)
