Freedom of Speech is a marvelous luxury of democracy. But, recognizing an enemy is vital to any country's sovereignty. The Alt Right, as a political entity, is being discussed wrongly in the USA and quite possibly Europe. The Alt Right is not friendly to democracy, it is a parasite the uses the freedoms of democracy to end life and terrorize populations. The Alt Right is another name for the enemy and the discussions in democracies need to reflect that and not embrace it.
Hate speech is protected, but, it is not supposed to be a method of governance.
Those that practice hate speech as a form of governance are incompetent to govern. Hate speech removes the rights of targeted Americans and places them in an envelope of danger.
