Basic, loose ideas of innate human rights existed prior to democratic states, but were usually superceded by the fact that the ruling class (especially any sitting tyrant) could literally just snap their fingers and override them. On that note, tyranny of the majority still requires giving voting and/or vetoing rights to a majority of people on a specific motion, which a dictatorship is antithetical to.
A democratic republic is still, ultimately, a "democratic system" of government -- as per the name. Yes, not an absolutely democracy, and the right to vote has never been completely universal, but the system of government still allows for some measure of democratic power, which rises and falls depending on how conservative or progressive the current era may be.
A good number of the Founding Fathers wanted commonfolk, women and certain ethnicities to be completely without any input into the democratic system, so what they would or wouldn't be disappointed with is rather "meh". However, I'm pretty sure that, say, a Black woman who is able to vote for or hold public office has a muted appreciation for how that system has expanded, even if imperfectly.
