BD, would you be concerned if, in America, Muslims were the majority? What if they held prominent positions of authority and had numerous lobbies in their corner? Any concern for how that might affect you and your family, just due to the direction of the government? What if your Christian vote was lost in a sea of Muslim votes? What if this became a "Muslim country"?
That could happen and it is the right of every American to choose that. Yes, I would speak about it because I would be concerned with their salvation. Would I respect the votes of Muslims? Of course, just as I respect the decisions made by atheists that hold positions of authority. Until...it violates rights. I think that it is the right of people to teach what they believe. I am not opposed to teaching evolution in school. But why not teach the study of creation in school as well and let the child see both sides of the issue?
However, atheists are not concerned about anyones salvation. Can you prove that religion slows the progress of man?
