An unconditional right to say what one pleases about public affairs is what I consider to be the minimum guarantee of the First Amendment.
Hugo BlackThe "establishment of religion" clause of the First Amendment means at least this: Neither a state nor the Federal Government can set up a church. Neither can pass laws which aid one religion, aid all religions, or prefer one religion over another. Neither can force nor influence a person to go to or to remain away from church against his will or force him to profess a belief or disbelief in any religion.
Hugo BlackThe history of governmentally established religion, both in England and in this country, showed that whenever government had allied itself with one particular form of religion, the inevitable result had been that it had incurred the hatred, disrespect and even contempt of those who held contrary beliefs.
