Do you not see the First Amendment at all? Shall we just get rid of the Constitution then?
The Constitution written by Christians...grounded in the Christian faith? I think they wanted to allow for a freedom of religion because they saw the turmoil it had caused in the past in European history...as well as in theirs. But I do not believe they wanted "freedom of sensitivity."
I'm not sure what you mean by "freedom of sensitivity", what they wanted was a separation of church and state, they wanted individuals to be free to choose whatever they wanted.
Thomas Jefferson wrote:
"Believing with you that religion is a matter which lies solely between Man & his God, that he owes account to none other for his faith or his worship, that the legitimate powers of government reach actions only, & not opinions, I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should "make no law respecting an establishment of religion, or prohibiting the free exercise thereof", thus building a wall of separation between Church & State. Adhering to this expression of the supreme will of the nation in behalf of the rights of conscience, I shall see with sincere satisfaction the progress of those sentiments which tend to restore to man all his natural rights, convinced he has no natural right in opposition to his social duties."
