Just for the record: I have a disability (blind), and from my point of view, there is one category of people that tends to behave completely inappropriately towards me, and those are "believers". I tend to avoid them whenever possible, because they tend to treat me in a very disrespectful way. They dont notice, because their faith has trained them to treat me with a certain patronising spin.
TL;DR: Not all "disadvantages people" actually want the protection of religious fanatics.
Thats part of it. Unwanted help is definitely an issue.
However, it doesnt end there. The more religious a person is, the more they take their time to explain to me how bad they think my situation is. Patronisation, pittying, and a general attitude of looking down at me.
