People don't feel safe having prejudices anymore because the world is becoming more accepting of differences. At the same time we are becoming more accepting, people feel like they are being suppressed because their limiting beliefs are no longer deemed acceptable. Those in power rarely go down without a fight when people become equal to them and they experience the slightest loss of power- that same loss of power which those now empowered people have felt their entire lives. Donald Trump has given permission for people who are losing their position of power to minority groups to be justified in their fear and to act out on it. And, when the media sensationalizes it, it reinforces the behavior and rhetoric. It's like an endless cycle that is gaining more and more momentum.
