"Yes it is, it is acceptable of a government to make an official statement that no existential position or system of ethics not based on reality is to be imposed on others."

I don't see how it would be 'imposing' something on people to require that the government obey and follow the spirit of the 1st amendment, and not take any official stand on these issues.
