I have never used a spinner, but it really hurts my heart to see something that would have helped so many kids who have trouble with classes due to mental disorders be turned into a "trend" by parents and other kids who are neurotypical/do not need them. The constant theme of minority groups becoming "Trends" within the groups that oppress them is a serious issue and it's upsetting/really hurts people. Seeing neurotypical adults who make fun of people with autism or PTSD turn around and use spinners is sickening since they don't want anything to do with us but then turn around and use our coping methods and change them into toys. Just like how white people have been praised by other white people for wearing braids but then the same people turn around and get black girls kicked out of schools and refuse them jobs because of the same exact hair style.
This is exactly my issue...I've seen varying perspectives on this but I think when things like this get overtaken by neurotypical kids/teens/adults it seems to lead to trends and bans and that always negatively effects the divergent people the most. Where fidget toys really help me to keep calm and focus, using one just gets seen as playing and distracting or being taken in by a trend and its then hard to explain to people that you really need that grounding.
