You're raging against this in very general terms. As a snotty European I would throw in suspension as a disciplinary measure for humans in development, as all children in schools are, should only be the ultima ratio. So learning there are time limits on suspension terms for kids with disabilities sounds absolutely insane to my very snotty European ears.

If a school system in the US implemented inclusion without individual review when it isn't working or is too disruptive for the other pupils, then I don't mind you putting that term in inverted commas that much. I think you're on the edge of ableism there though. If you're trying to win an argument at a school board meeting, you might want to keep that in mind.

Many school districts are cash poor. They are being asked to follow guidelines for all sorts of things, not just the topic we're discussing here, without also being given the financial means to fulfill them. The American teacher asking for go-fund-mes for classroom material is an established meme. That's why out of principle I cut teachers and admins in the public school system some slack. So rather than running the risk of being misunderstood as an angry ableist, channel your anger at the people who make political decisions that affect your school district. Because I'm very confident at the heart of virtually every school related conflict lies chronic underfunding.
