There is no such thing as total security, and so there is no such thing as total privacy, nor anonymity. And at the same time, there's no way to completely track everything done online (or in person), as there's always a way to cover your tracks. But none of that address the human behavior aspect.
If you have a room full of people and someone is saying something bigoted, a couple things happen. One, if others agree with the person, they will clump together and gain strength. Two, if they are shunned, they simply go to a corner of the room where nobody minds them and they're allowed to continue. The bigger the room, the more people there are, thus both of these factors simply amplify the behavior. And the internet is the biggest room in the world.
It's quite easy for this stuff to propagate, anonymous or not. Even if public shaming worked they'd just go underground. Most people who have shitty opinions actually believe in them and will defend them if challenged. So whether you 'expose' someone or not won't typically change their thoughts, and thus not their behavior either.
