I don't see how suggesting someone would rather not have a disability is "gross". These kinds of overreactions don't help the situation. Try arguing a point rather than coming from a place of emotion.
Arguing that someone with a disability should support this because they might benefit, without reason or evidence for that, is an appeal (only) to emotion.
I find it ableist, to use disabled people as an abstract hypothetical grouping in this way, only to support a point that is indefensible any other way.
If you don't want me to have an emotional reaction, don't set up an emotive point.
Your point in the other comment was that you would cause suffering to and sacrifice "hundreds of billions" of primates for a small chance to heal yourself.
That's clearly not balanced. I personally don't think that animal testing as it exists today, and given the complete lack of direct results that it has to show us, is balanced either.
Do you really value yourself, as a human, trillions of times higher than a chimpanzee? I don't and won't respect that. You saying that, out loud, only makes me wonder how much you internally value other humans.
