One website is an indicate that the right trolls more than the left? Gonna need more sources than that. Neither link says who trolls more than the other. That's a claim that is incredibly difficult to monitor across the web. 4chan is not a right-wing site to troll the left, it's a site that trolls everybody esp. by creating itself as this massive, unstoppable community during important, controversial events (like net neutrality). The site only really shows just how powerful it is when they feel the need to right a wrong by doxxing trouble makers online (like a monster throwing an animal into a river in a bag). It's a site that basically sits on the edge of the normal web and the deep web where everything is free game to be ridiculed and no one cares about your political stance. You can post about Trump or Obama and someone will insult you. Reddit is viewed more Left because a neutral-sounding sub such as r/politics is really just a place to call conservatives scum as the Top comment, and Controversial comments are the opposite from right-wingers. The only subs you can't troll are the ones clearly defined on their stance. Thankfully, most subs will ban you for political debate if it has nothing to do with their subreddits.
