Fuck Christians, fuck all religions but that's not true everyone has a right to tell someone else anything they want. They don't have the lawful support to "force" anyone to do something they do not want to do and vice versa. Imo, the subject that will always go back and forth will be abortion because opposition to it will always believe they are the voice for the unborn, I know atheists against abortion so it isn't just a religious perspective. I think they also fear an existential threat considering birth rates are already drastically declining ever since the baby boom era. Everyone has the freedom to express their beliefs and principles and morals but nobody has the mass support to force another human to do something they don't wanna do, it should be as simple as that.
