Loopback?

The most common discussions about Deaf studies in Poland are placed onto language-based discourse. Many issues are taken on: impact of sign language for deaf children (with topics related to paretning, raising and educational issues), language-related psychology and identity topics, let alone dynamically emerging linguistic issues. I'm serious glad of this, simultaneously, I'm serious concerned of this.

Linguistics is most widely recognized as the key issue in Deaf everyday life. Today, I browse through Ladd's book, Understanding Deaf Culture". There are some pages with photos, an one is the photo of kid who wear banner "We still have a dream". Looking on this kid, I realize, that in Poland many kids still share this dream, but... is this dream an loopback of advantages of sign language over oralism, endlessly proved by scholars?

I'm confused.
