I don't care that other people are religious, so long as they are respectful of my right not to be.
I don't care that "under God" is in the pledge, or that "In God We Trust" is on our money. Just don't make me say "under God" if I don't want to and don't insinuate I'm not a "real American".
I don't care if a group of muslims want to build a worship and community center near Ground Zero. There were muslim casualties of that disaster and no I don't mean the guys flying the planes. Muslims worked in the Twin Towers just like atheists, christians, jews, buddhists, and so on. As far as I'm concerned, all religions are basically silly, and I don't accept the premise that one religion gets to disavow its nutjobs (christians) while another isn't allowed that same priviledge.
I don't care if a politician is or isn't religious as long as they will protect my rights to be non-religious if I so choose, will stand up for teaching real science in schools and not some creationist or neo-creationist clap-trap, or generally understands we live in a secular democratic republic and that is exactly how our Founding Fathers intended it.
I don't care if a teacher is hyper-religious, so long as they leave the sermons in Sunday School.
I don't care if my kids' school has a christian club, so long as my kid isn't exposed to official pressure to join it or attend its events. Peer-pressure is something else entirely, I don't hold a school responsible for one kid trying to convince another kid to do something, so long as that 'convinving' doesn't cross the line into bullying.
