I don't think it is "self righteous" to note that a discussion of this kind will have people saying we're the "mean party" when we pick on other people's kids. It's not right to pick on the Bush twins, and it's not right to pick on Chelsea, either.
We're above that.
Think about it. The left does it all day long, making fun of the looks of Linda Tripp, Paula Jones, Katherine Harris, Ann Coulter, deriding Laura Bush (a gorgeous woman!) as "frumpy" while hailing that moonbat Tahrayza as "sexy". They demean the looks of the person in order to dismiss the message they bring. Whatever intellectual points do you think you score when you pick on someone's kids? Who do you think is "convinced" that conservatives are more logical with this kind of tripe? Do you think you're showing anyone how great your arguments are, or just that you can sink to the same level as DU'ers?
I hope this discussion is not proving that we can be as puerile as the left.
The problem with what you are saying is that Chelsea Clinton IS in politics. You might as well suggest that we leave Hillary alone.
