These web pages follow a convention practiced by many high-profile netizens, including Scott Adams of Dilbert fame.
Simply put: whenever I feel an offensive word is called for, I happily substitute the name of an offensive politician.
The justification? Scott says it best:
The beauty of this approach is that they can't easily ban these new naughty words without changing their own names. I know I could get in trouble for suggesting such a thing, but I don't give a flying Clinton what they think. And if they don't like it they can come over here and kiss my Gingrich.
