Locations? Specifically in "atheist communities" - you know, just like American Atheists did with the Jewish and Muslim communities in the news.
Now personally, while I support free speech, there is a thing called common decency that all of the people that payed to put up those billboards spouting hate should learn.
Not believing in God is not anti-American, nor do I believe that being an atheist means that you hate your country. Messages like that are just as stupid as the ones that American Atheists payed for, no matter where they are.
