I'm not sure we can agree on all that. We're still burning witches (eg. Bin Laden), and figuratively (Assange, Manning, Snowden etc), steadily removing a due process that assumes innocence that was created 800 years ago. Star chambers have re-emerged to hide the crimes of oligarchs too, particularly in the UK.
Slavery still exists, it's face has just changed. The modern slavery is economic slavery - the requirement to labor, and be taxed on that labor in order to survive.
And to suggest that segregation is no longer an issue is disingenuous. Take a look at Israel for example, a great role model being "the only democracy in the middle east".
On top of not being much more civilized than our ancestors, each year, people still celebrate the life of one of them, whose work was the mass murder and torture of aboriginal Americans. Very civilized, and patriotic. Yes, patriotism! What wonderful social values we have in the civilized world.
I don't know if we should say civilization is a binary value or a spectrum, but I'm pretty sure that one which routinely conducts murder and celebrates it is definitely on the "non-civilized" side, according to my understanding of the word.
I can probably agree that democracy is slightly better than what was had in the past, but democracy no longer exists, it has been eroded now to the point where recovery is not likely.
