In response to the idea that Jews would be terribly offended by ex-Jew "I chose to change!" propaganda:
I encourage you to check out the Jews-for-Jesus ads (I've seen them in NYC subways and in pamphlets which I collect for fun). They include pictures of smiling former Jews talking about how upset their families first were when they found Jesus, but that everything is OK now that they have the Lord and Savior in their life!
These things really do exist.

On another note, I am always perplexed when I meet Jews who are sexist, racist, or homophobic (and there are lots!) As though being persecuted hasn't taught us anything.
