1. it is not an "implied joke"
2. Chelsea was fair game here
The original poster's observation is correct (and I believe Chelsea was 16 years old, or younger).
If you still believe the poster was correct, you are missing my point completely.
The Dem rumors vs. the morph.
One implies the 16, then 15 year old child, daughter of Sarah Palin, engaged in sexual behavior leading to bearing a child.
The morph DOES NOT imply Chelsea doing the same, nor does it smear HER reputation, it goes after the adult mother. See the difference yet?
The KOS is perpetuating rumors aimed at smearing children, not the parents. As I said, that's as low as one can go, and is NOT the equivalence of the “morph” at all.
