Anyway: The worst thing an organization's leaders tolerate is what that organization becomes, and the blast radius of a single toxic contributor is huge and largely invisible. For everyone who speaks up to say this behavior isn't acceptable, there are dozens or hundreds of smart, competent people who peer into your community, see that this is how you live and move along without your ever knowing they exist, on their way to a better life somewhere else.
We don't have to live like this.
