Disability activism can be hard even amongst allies(and even less ableism educated disabled people)
I think one of the difficulties that you can encounter when discussing disability activism and discussing an issue is people you thought would be allies sometimes even disabled people themselves being the ones to dismiss it as not real. This is often because though they are allies, it conflicts with their surface level reading of a situation and they dont understand how it relates to your needs or even worse how often it might be something that is recurently being used to push for the removal of accomdations or violations of disability rights.
Part of this can come from people desire for the perfect accessibility tools too. That should be strived for, but many people have an odd kind of modern ableism where they want to limit all accomdations unless it is normalized or pwrfect no matter if it does legitimately help a person. We often see this perpetuated through scripts about a specific accomdations being not designed solely for disability for example. Of course we do need to pressure disabled voices to be heard in the design of these things but thst shouldnt be used as a excuse to remove accomdation but instead to improve accomdations.
I think these types od situations can be stressful in a way explicit discrimination isnt because they are actually coming from your allies but yournallies without realizing it are perpetuating ableism and when you confront them on that or discuss the issue. They wont get it because they already see themselves as supporting disabled people so their actions couldnt be antidisabled in some way
