When it comes to recruiting, Christianity has it going on.
On one hand, you have Jesus hanging bleeding on the cross, appendages nailed and face distorted in pain. That's some graphic shit if your not used to it. The open casket is also kinda scary, Jews don't do that, so I didn't even see my first open casket until my mid twenties. Pretty freaky.
But Christianity also has cartoon characters, you know, like Santa Claus, the Easter Bunny, the elves and reindeer. A spoon full of sugar helps the medicine go down, in the most delightful way (I'm quoting Mary Poppins so you know I'm right).
Jews, on the other hand, have the Holocaust, the angel of death, fasting, atoning, 500 years lost in the desert, public circumcision, and a holiday based on the lights staying on. When given the choice, how enticing is that? No wonder we're a dying race.
The Hanuka bush was a nice try, but the cartoon characters is what reels them in. So there you have it.
