So what? The same thing happens in families of republics. Look at Bush - we all know that he doesn't like blacks and homosexuals. His two daughters are drunkards (just like Bush was). In 2001, Jenna Bush (under 21 at the time) was charged with being a minor in possession of alcohol. later, she was charged with using a fake ID to obtain alcohol. Her twin sister has also been charged with similar offences.
In 1963, Barbard Bush - Shrub's wife - illegally ran a stop sign, crashing into another car and killing her friend Michael Douglas.
The Windsors might have their family problems, but so do the Bushs.
Also, when was the last time you saw a child or grandchild of the American President serving in the military, as our Queen's children, drandchildren, husband (and even the Queen herself) have done for many years?
Ok..you win. Your queens are better than our queens.
