I have no data to back this up, but I would guess that no, they are not. It’s not that racists are immediately disgusted by the actual skin color or features of other people. Racism is a learned behavior that “others” people that are not in your “tribe”. You can also often tell if someone is a different race, by their accent, the way they speak, or the way they act. A lot of racism is based on stereotypes and tribalism, and the excuse of racists is that their dislike is based on their actions and culture, not their actual race. I also suspected that, though many blind people are very social and lead fulfilling lives, on average they are probably more used to being shut ins, or at least limited to a small amount of familiar areas. And the best cure for racism and xenophobia is travel. So yeah, I’d say that balances out the potential loss in racial discrimination based on not being able to actually see the person.
