4chan has a handful of good boards on there that are not filled with racist diatribe. You're going to find content on there long before it hits anywhere else - if it hits anywhere else to begin with. Even /pol/ itself, prior to the 2016 election, had plenty of interesting discussion. Hopefully once this drama blows over it will return to a more nuanced place. As for Vice trying to paint /pol/ as this ultra-edgy super radical place, I can't help but laugh at how hard they're trying. It's a board full of early 20-something year old shitposters. Give up the nonsense RWDS-tier fearmongering please.
