You.Are.Dumb.
Noting it is a "constitutional federal republic' DOES NOT exclude it being a form of democracy, which IT IS.
There are
MANY FORMS OF DEMOCRACY, and simply citing which subset of democracy the US is, which falls under
Representative Democracy, as if that then precludes it being also a Democracy is just more dumb, from the dumb party derps.
Almost all countries that we call Democracies in the West and First world, have a form of Representative Democracy, and thus by this derp reasoning, none of them are democracies.
Again this position is Marjorie Greene and Boebert level dumb. Congrats on that.
