It seems when it comes to anti-atheist protests the matter of grammar may not matter to some if the experience of an atheist group in Florida are anything to go by.
Protestors object to an atheist billboard because they say it tells people: "Don't believe in God."
If you look at the picture in the news report you'll see what it actually says is:
"Don't believe in God?
You are not alone!"
That little question mark makes all the difference.
Perhaps "grammar fundamentalists" should take to the Florida streets too.
