Yep. I completely agree that in real life, a woman with the access and abilities that Barbara Gordon does in the DCU, would probably have found a way to be walking again (without being half-robot). But, to me, the meta-reasons outweigh that internal logic. (I wrote an LJ post about Barbara and disability back while there was still a bit of talk about her becoming Batgirl again, basically outlining my meta reasons for why she should remain in the wheelchair.)
When you say stuff like "I like comics that humiliate Barbara" as you did upthread, it just sounds like you hate her and not the choices that writers, artists and editorial have made over the years. And even if your reasons for hating her come down to what you believe to erroneous choice on the part of those with creative power, it still often comes off as just "I hate that woman and I want bad things to happen to her"...and that does make me uncomfortable, I will admit.
