I have to say I’m bothered by Christian leaders saying that the US is “distinctively Christian”, as I am Jewish.
The US should be able to welcome, and be comfortable, for people of all religions who don’t want to change our society; the same for atheists. (Note I’m saying “people… who don’t want to change our society”, not “religions”. I refer to Jihadists, not all people who identify themselves as Muslim or any other religion.) And there are some atheists who want to change our society; I reject them as well.
