I mean like, there are a whole lot of shitty books and you can argue that writing has given them that platform. Just as there are the same amount of idiots in the world, there are the same amount of not more of intelligent people.
I think social media does a service. Before, you couldn't tell who the idiots were without meeting them and talking to them for a while. Now you can just browse a Facebook feed and be like "Yup, he's a fucking Nazi." The ones it gives a platform already had a platform; they started out having meetings then upgraded to printing pamphlets then moved to broadcast radio, then became respected talking heads on cable TV long before social media showed up. Social media is interactive though. Used to be I had to write a letter to a personality's PO Box to call them a fuckstick, now I can just leave a comment.
Now people feel like they can walk up a post as many theses as they like, it's outrageous!
