I disagree. While it is clear that no single faith can be favored in a democracy , acknowlesgement of a creator and an authority beyond humans is crucial. Up until the 20th century the US congress held church services at the capitol hill for example. Government has no bussiness meddling in religion and vice versa but just as religion must acknowledge government's limited authority, government must also acknowledge that all people are created equal and govenment's authority is not an absolute rule over people and that people are properties of their creator (whoever they believe that is) not properties of government (as they are in completely secular regimes such as China and NK).
Ethics itself means nothing without a legitimate moral authority so how can secularism lead to ethics? Either you accept a higher power exists and by that logic define ethics that allows coexistence between religions or you embrace secularism and tell religion there is no higher authority other than government and their religion is subject to an authority that rejects the absolute moral authority religion embraces. In other words you are expecting religion to self contradict in order to comply with secularism,which defeats the whole point of coexistence.
