You're probably not wrong. But I think we should recognize that what is humanity is rather fluid. If you were to talk to the 15th century clergymen, I think they would tell the horrors of printing press and how it has/will break humanity. And they wouldn't be wrong either. Humanity evolves, and, well, that's it. And overall, hopefully, and this is where we hopefully can effect positive change, we can steer the change to more humane, and moral direction.
I think they simply shone a light on human nature. Those aspects were there and still affected people, but we had the illusion that we were rational humanist actors - and even then that was only in the west. the internet simply shattered the illusion.
