I noticed and collected a lot of memes with emotional posts on Facebook after the historic SCOTUS decision on gay marriage. The funny thing is, they are posted in proud defiance or opposition, when everyone already knows and agrees that the SCOTUS isn't the supreme being and it can't change God's laws.
(Like screaming WATER IS WET!! And we're all waiting for the punchline, the point of difference, the reason for the outrage, while crickets chirp.)
That is PRECISELY the beauty of the separation of church and state. BOTH institutions are protected this way. When/ if we have a Christian president who rules strictly from the Bible and not for the general public well being and freedom, that is when Christianity is threatened MOST (unless we install him as supreme leader/dictator, ditch democracy and go totalitarian, only THEN can rule stay in the hands of Christians. ...well if Christians can muscle through coups, constant civil war and instability...) because with every election you could get a brand of Christianity you think is evil, or Hindu, Buddhist, atheist, or Muslim and all the laws would change.
As long as we value separation of church and state, our right to worship- or not- the way we want is protected, no matter who the top guy is.
It is often said the church is not a democracy- so, if you want to live in a democracy, why do you want to have a Christian president making laws as though he were ruling the church, making church and state one? It might be convenient and simpler for you (if you are Christian) to live in a land ruled by the Bible and have all sins be legislated against, to jail liars and murderers alike, give the death penalty to gossips and homosexuals alike, but that land is not, and I hope will never be, the United States of America.
