This is a strategy imposed against racism and violence. If conservative voices include a lot of racism, then, yes, I guess they should stop being racists.
There was literally zero racist activity on The_Donald. The mods were very transparent and showed EVERY ACTION once they hit quarantine (to show they didn't deserve to be quarantined). The only racist posts came from new accounts / people who had never posted in The_Donald that were immediately removed by mods.
