Respect right back at you!
My thought on why they might have made that choice: Perhaps the choice to stay off the stage felt like erasure to them? But also, disabled people (whatever their disability) have worked for a long time to be seen first as people, and not as merely standard bearers for their disability. Perhaps these two people were excited to get a chance to show their political beliefs in a public forum as people (even though, one, they're obviously being turned into tokens for the photo op and, two, those political beliefs are deplorable).
So I don't want to shame THEM.
