I have tried to re-cast this question to make it more general, and less related to my own experience. Do I need to do something further to trigger a 're-evaluation'?
The edited question has two two related parts that make it broad
What unique aspects of post- PhD academic culture allow bullies to persist?
What can be done to end this?
Even if you split the questions, it is still very broad. A much better, but less general question, would focus on a particular type of bullying, or even single incidence of bullying, and ask something like, how/why did this happen, or how to avoid it in the future, or how to deal with the consequences. We have a lot of good questions about sexism and advisors "stealing" ideas that probably constitute bullying.
As it stands now, the question seems to be inviting discussion and is not a good fit for the SE format.
