"similar to criticizing blind people for being bad at riding bicycles"
I am not aware of a debate where people get blamed for being blind.
But it makes sense to me to critizice people who want to ride bikes but have not the ability to do so in a safe way, that not endangers other people participating in street traffic.
Now if a blind person learns to ride the bike reasonable well (with technical help) so he or she can actually ride with safety and not endanger others - fine with me and probably most other people.
