"There are a number of people and groups who walk the line between alt right and alt lite, to the extent that it’s not always easy – or even possible -- to tell which side they’re on. The Proud Boys, an alt lite, right-wing activist group founded by Gavin McInnes and dedicated to “Reinstating a Spirit of Western chauvinism,” is a good example of a group toeing that line; some of their members support alt right figures and events, while others have made a point of steering clear of anything associated with white supremacist beliefs."
