Perhaps reframe it as pride in still living, surviving, sometimes even flourishing in the face of a society that will not accommodate you. It's also a really direct counter to the shame that is so prevalent amongst disabled people. I have an invisible disability and it's taken many years for me to even accept that I am disabled, nevermind be happy with it, you know?

I wouldn't call it pride, but I'm aware that a not insignificant portion of people would have just committed suicide rather than experiencing what I've gone through. Especially people who pride themselves on abilities that depend on being healthy. To experience something like years of torture and then to find a way to keep laughing is not insignificant.

Why shouldn't a person be proud? They constantly use lateral thinking and creativity to maneuver through the world, and their disability is part of their unique identity. Their disabilities cause some of their problems but society causes more. Living with a disability doesn't make a person less worthy of respect, self-respect, or pride in who they are. Having to face attitudes like yours every day is why we need to have celebrations of disability pride.
