As religions go, I don't like Islam...but they would have every right to put such a billboard up. I certainly recognize the distinction between Islam and modern Christianity in their treatment of members of other religions, which is why I prefer to live in a country dominated by Christians rather than one controlled by Muslims.
While I plan on traveling the world when I retire in a few years, Saudi Arabia is not on my bucket list!
I agree with you.
But, the way I see this specific topic, the atheist bill boards are hostile. There’s an anger about them.
Ultimately, atheists I wouldn’t trust any more than Islam if atheists were the dominant belief in a society.
In the US, atheists generally retain judeo Christian ethics due to their environment. But as that influence wanes and atheist numbers and strength increases, I would be worried to be subject to such a society.
