Politic as religion are 2 subjects that always create conflicts between people even good friends. The best is not talking too much about politic and religion and to be very careful.
In july someone posted in this forum a link about "defaits" of France, it was not really nice for French people. But it looks funny for everybody else.
In 2003, a lot of US people and English people hated French people because the French governement did not want to support the war in Irak.
The French products as wine, champagne or foie gras were boycotted in the US. And this year, very few US people came in france for vacations.
A lot of people pay a tribute because of the decisions of their government. I think that it is enough and we are not going to get in war with our best friends just because one is pro-Bush and the other one is anti-Bush.
