Probably closer to 50% where I live. When I went shopping yesterday, large numbers of people were very likely not Christian. We’ve got a Christmas-like tree in our office, where Christians are probably around 20% at most of the staff.

Have you seen an optometrist?
That’s a pretty rude thing to ask an apparent blind person.
