Err, it's the land of the free, they're free to learn whatever language they want and expect communcations access for it.
Besides, the VRS users HAVE learned ASL -- which is AMERICAN sign language -- and are using it to communicate with their community, family, and friends who are spanish.
Many legitimate businesses do their business only via Spanish.
Don't discriminate against those who have come to this great country just because their FAMILY or FRIENDS don't speak English.
