In the eighteenth century no one could get away with blatant accusations against royalty, so the pamphlet writers had to be a bit creative, using satirical drawings to get their point across. If the tabloid journalists of today had to do this, perhaps we would all be a lot smarter from trying to figure out what they were trying to say. Some things never change though, as it still is almost always women on the front of the tabloids in the the checkout line at the grocery store.
In the film Marie Antoinette she is shown to be actually having an affair, something which was never actually confirmed. True or not, I wouldn't really blame her. Being stuck with a gay husband really gives anyone the right to have an affair.

Sadly, the queen was blamed almost entirely for the French Revolution. This is outrageously unfair, as it's pretty obvious that one person can't be responsible for all the problems of a country.

I think a lesson that can be learned from Marie Antoinette's sturuggle to please an unhappy pulic is that we should never judge another until we walk in their shoes (and if it's Marie Antoinette's shoes, they would be fabulous). However, I do encourage judgement of fashion, please continue to keep that up!
