all autistic people need support, and some need support in different areas than others. but labeling autistic people as high functioning or low functioning based on what support they need is harmful because it can cause people who are referred to as high functioning feel as if they don't struggle enough to deserve support and can cause people who are referred to as low-functioning to be infantalized and not listened to by allistic people. not only that, but the needs of an autistic person can change day by day, so they may need more or different supports on one day than another
