Not offensive at all. I've used similar ebay titles in my listings to help sales, not sure that it helps any, though.
I agree with Jay. Ryan Braun is not Jewish. He was raised Catholic as is his mother's religion. Many of the so called current Jewish players are not raised Jewish. Those players have a very small Jewish heritage that they then mention when the media asks them. But they do not consider themselves Jewish.
The seller is way too high for this lot. Definitely not worth what he is selling it for.
