It’s pretty common for modern Western governments to be both of (Democratic, often also Federal) Republic and (Representative, sometimes with minor areas of Direct) Democracy.
You're talking to one, who knows others.
Democracy as defined is a goal we have. Not something all (maybe most!) Americans would claim to enjoy.
Honestly, I can't even think of an alternate(, but still charitable,) interpretation of:
"Shouldn't it be very easy to vote to fix that in a democracy?"
Suggest one, if you can?
> most people
to
> a nonzero number of Americans
Holy motte and bailey, Batman.
> "Shouldn't it be very easy to vote to fix that in a democracy?"
That hasn't been the dominant use of the term for centuries, but, sure, you keep pretending.
It is also a republic. It could be a republic even if it was a pure direct democracy somehow without "issues" - in fact I struggle to see how a direct democracy without issues could be something other than a republic.
What, HOAs?
