They, (people), did more harm than good throughout history. they started sooo many wars its nuts! Plus, we have all this global crap going on. We have global warming, that war with ISIS, there is a religion thing.
We have an amendment that allows women to vote, we have legally ended racial segregation, and JimCrow laws. Do we still have room for improvement, concerning equality? YES, but ask any female or minority if they'd prefer to return to the ways things were 100 years ago and I think they'd agree that things are better now.
