Does that include those in the media/press?
The media are already doing their best, and if it were not for them, the thug/feral human underclass would not have grown so stout.
There are many other assistants - liberals all. Various professions who feed off the continuing misery of others, politians who need the festering underclass for power and re-election. It goes on and on.
There's the thug who actually stabs or shoots, and then there are the many who enabled said thug to be able to do his deed. It's a network. Doesn't mean that any of them does not share responsibility. They are all responsible, and each of them can at any point decide to be a different person.
But the longer they remain as they are, the harder to change.
There is not only one danger, one enemy, one problem. But they are related. Like a poison diamond with many facets.
