Secular Collation for America is away for non-believers to have an influence in government. The free thought caucus is some what new and needs our support. Freedom from Religion Foundation is apart of the Secular Collation. Both groups have YouTube channels if you would like to get to know these groups.

Like most things it isn't a black and white answer. The true answer is yes, but not nearly enough. And certainly not as separate as the founders intended.

Can't really comment not being American but when I here the refrain of God Bless America it seems pretty clear to me where the constitution sits!

This question reaches into the center of our cultural majority. And the answer is that we have solidly within our majority culture the idea that we are a Christian nation. Even though we have enshrined in our Constitution a separation of Church and State there is no cultural expectation by the majority that there is an actual separation. Some minor legal challenges arise from time to time but the decisions, made in favor or against have not changed our cultural view. And our nation might be a theocracy if it were not for christians being divided into so many denominations, (more than 900 in the US), each with their own belief and all different from one another.
But to answer your second question there will always be prejudice of one sort or another. As much as we want others to be like us they are not. When they are not prejudice takes root. And as for the "under God" it is, on its face, meaningless because the "God" is not identified. It could be any "God" you want it to be. It is just culturally assumed that it is the Christian, Jewish, Muslim "God" Yahweh, (or any one of the other names their God is known by).

I think yes, basically. True, the separation isn't total. I don't see how total separation could ever be achieved. Elected officials are affected (in part) by their own religious beliefs.
It brings up the question again, "Does a public bakery have to bake and sell a wedding cake for whomever walks in the door?"
Our local school board (in Georgia, USA) begins each meeting with a Jesus prayer. I guess that's OK for now because everyone in the room is a Christian and there are no children present.

There are several issues at :

1. Political exploitation of people's religious/spiritual beliefs, whether it’s the addition of “under god” the Pledge, the addition of “in god we trust” currency, public prayer before conducting government business, and so on. This allows politicians paint America as “good” so long as we follow a god, while painting anyone who doesn’t have religious/spiritual beliefs, or contrary beliefs, as “bad”.
2. The collective ignorance of the general populace about what the first amendment says, and what it intends.

The two things are NOT separated. Look at this little considered fact. A man and a woman need to first apply for and then pay for permission from the State to get married in one of its business franchises, commonly known as a "church"! No priest, pastor, minister or other such "representative of God" may perform a wedding ceremony in that fake house of God if the couple do not first have that State issued document! Why is that? Why does anyone need permission from the State in order to enjoy a beautiful relationship with another? Why do a man and a woman need to be considered to be married by State actors, agents and operators of the legal system/Matrix, before worldly goods can be passed to the other at the time of body death?
Now, here's a question to ponder; Since there was coercion involved in the matrimony (coerced or tricked licensing), how can it be a valid contract? How can it be a valid marriage? ANYTHING which is alleged to be a contract can be vacated for fraud, threat, duress, coercion, mistake, illegality, immorality, impossibility, insanity or minority of age at the least. Anything which violates the five essential elements of a contract, void it. For proof of this, just look up the definitions of Contract and Fraud in Black's Law Dictionary. Don't worry, I'll wait right here until you get back after doing that.
The legal system/Matrix is its own undoing because it violates its own premises for existence in the first place and does so on a daily basis. The facts and logic bear me out here. The legal system/Matrix is supposed to be against crimes like fraud, theft, murder, etc, but yet it commits those very crimes every day that it's in operation!! Have you ever thought about that before? I doubt it very much. But logicians such as myself do!

I couldn't give a "yes, or no" to the poll.
Yes, in that there have been some strides in that seperation., but yet no, because there is always some religious nut with a political background trying to sly by the constitution.

I do believe that it will eventually get to a point where church and state are devided, but it will take baby stepps, and a LOT of court battles.

I just hope to see it in my lifetime.
