“Impose” is a harsh word.
But a democracy is where the majority rules.
In the United States of America, Christians are the majority, so Christians must rule in America and make sure that the majority position is the dominant position.
By definition, dominant means that it is the position that is the main position of the country.
Thus, in a democracy like the United States of America, where Christians are the majority, Christianity should be the dominant position in every facet of the society.
If the majority of Americans who are Christians are ruled under a secular or Jewish-agenda public discourse, then America ceases to be a democracy governed by the majority, but rather, America becomes a oligarchy where the minority (like secular people or Jews) rule over the majority.
It is important for Christians in America to make sure that USA does not become an oligarchy, where a few rules. It is important to ensure that Christianity is dominant in every law, every institution, and every public life. Democracy is the rule of the majority.
