We are not a Democracy. We are a Republic. Try to remember that.
the OP got the quotes wrong - the proper phrase is “our democracy” and it is used by democrats to denote the kind of socialistic “equity-based”, LGBTQ-friendly, second-rate country they want the US to become.
It’s the correct phrase when used in this context, it is not what our founders created. Try to remember that.
Not much difference. Every democracy in the world has a constitution and elected politicians who vote on issues. In a true democracy a simple majority decides every issue. There is no need for elected politicians in a true democracy.
