Psst! If a Republic is representative, it is a democracy. The problem you’re flailing to address is the confusion between “democracy” and “direct democracy,” which would be even better called a “plebocracy.”
The U.S., as originally and currently constituted, is a Republic, but it is also a democracy.
IF the WASP founders established a 'democracy', they would have so stated. The foundation was established in Genesis 1:1. Interestingly not one WORD posted in this attempt to take 'credit' for the founding of this nation comes from Scripture. Sadly, the WORDS of the prophets go unheeded and the nations deteriorate. The majority of the inhabitants of this earth are NOT going to like what is yet ahead.
The founders intent was summed up in very concise simple words RIGHTS endowed by the CREATOR, 'life', 'liberty', and 'the pursuit of happiness do not come from man, religions, or government democracies. Here is the problem, one must be learned in what the CREATOR required to be given these RIGHTS... and it is basic Constitutional 101 the law of Moses was their guide. NOT religious philosophy enslaving the life and liberty to religious organizations for their profit.
