The problem with yours is that it's the classic 'well, I'm disabled and so are my kids, and I don't need any of the stuff that you get, so therefore neither do you'. Every person is an individual, with individual needs and problems. Your life is not the same as @Kreepture 's life.
And when a poster gets irate because of the swathes of hateful ableist posts that you get on threads like this one, when someone gets tired of being told that they don't need this, that or the other, and that their every purchase should be monitored just because they're disabled... then it would help to understand that the anger sometimes slips out. If you've read this full thread (and I really hope you have) then you will, I hope, have seen for yourself the (wilful) ignorance that many people have around disabilities. And being disabled yourself, you'll show a bit of support and sympathy.
If you can't do that, you're part of the problem.
