There is no room in any society for hate and hate speech that insights people to commit violent acts is sedition. In most democratic societies, sedition is illegal. I fail to see the difference between terrorism, spawned by ideology and seditious behaviour that, in turn creates violence against any part of a society. It is all the same, terrorism, designed to terrify people.
Trump has scraped back the thin veneer on US society and exposed the vile hatred beneath that some alt right members harbour against anyone but white, wealthy, mostly male people and all under the pretence of being Christian. If they were true Christians they would realise that Jesus was from the Middle East and was dark-skinned. That in the Bible, Jesus talks of all men being equal under God. Jesus, to all intents and purposes was not white.
Maybe also the fact that scientific research has shown the birth of civilisation eminating from Africa, that Africa is/was the cradle of civilisation and that our ancestors were all likely black, is why science is being denied by the Alt Right, as part of every education under their rule. This ensures complience from the next generation and is denying children the right to a full education. Mind control of the masses.
