I’m of two minds on this. The folks being open about their hatreds and biases means we don’t have to put in any effort to identify them. They tend to underestimate how long going on the record lasts, too. 
Still, the ones who smile in people’s faces and stab them in the back are more dangerous in many ways. That’s especially true when they are able to cover up their activities, making it difficult to determine who inflicted the wound. While the illusion of civility and tolerance lessens the daily stress of those being targeted a bit, luring the sympathizers and supporters into the light makes them much easier to hit (in the wallet or elsewhere).
