The Internet is destroying democracy Controlled newspapers and TV with a narrative to push
Modern(and semi-modern) democracy likes to pride itself as a successor to Greek democracy but this couldn't be more false. Greek democracy was an aristocracy of a few educated, intelligent men who would personally meet their candidates and get a first account of what they were voting for. While in modern democracy everyone, without any barriers, is allowed to vote. With this extended voting pool, most don't understand the issues at hand, let alone each candidate's views and proposed policies on them. Most votes would be casted based off emotion or appealing to friends/family/co-workers. If they did, they still wouldn't have anything close to interaction with their candidates, the closest would be a scripted debate or the sort. They're voting for a perceived, media-based image of a candidate.
So modern democracy is very spoon fed and halters the facilitation of ideas. The internet undermines this by allowing unlimited sources for information, going much further than the mainstream media. In this system of immediate, relatively unmonitored communication many false ideas/information will be spread too, but it's illogical to say this started with the internet. One thing that has clearly scared the mainstream media since its very advent has been the internet. They're not scared of people having "wrong" views however, they're scared of new, different views. And, even worse, these people with alternate views can organize through the internet, and could spread their ideology further.
Even in the past, partakers in this democratic system have been hardly "informed". Their views are merely regurgitated and socially influenced. With the internet, people with so many sources of knowledge at their disposal from every source of information can strive for a genuine understanding of the world rather than accepting whatever is said around them as fact.
