There have always been such (it is human nature) - but right now they feel bold enough to speak and act, whereas previously they had been too afraid and embarrassed to do so publicly.

In South Carolina, various KKK-like groups said in advance that they wanted to kill people, wrapped barbed wire around baseball bats (in order to better kill people with), showed up to kill people, then actually killed people, then bragged about having killed people... Oh right, but the other side was not successful in securing a permit for their peaceful protest, so you know, there are "many sides" to every issue I guess.

Misinformation/brainwashing techniques are powerful. Like if you believed that a particular type of human was the root of all evil in this world, then you SHOULD want them dead, under those circumstances... right? You do not bc you know better, not just about that one group but more fundamentally that it is ideas that bring about evil, not people. But the people killing people do not know that, and it is to the advantage of others who seek power, and want to use the army of sheeple to advance their own agenda, for those sheeple to not know that either.
