Rise above it.
Here's the lovely Sarah in a picture published a few months ago in Runner's World magazine:
Now, I guarantee you that a few FReepers will comment on her looks. That does not mean that Free Republic is not a serious on-line community, or that FReepers pay more attention to Sarah Palin's looks than to her conservative issue positions and political courage.
FReepers are free to post as they wish, so long as a certain amount of decorum is maintained; I would posit that making fun of Dede Scozzafava's physical appearance, or engaging in testosterone-induced praises of Sarah Palin's looks, are not the equivalent of racist posts or personal attacks on fellow FReepers.
