Yes, but remember that social media is a platform for people to post their opinions. Its not about whether they post something true or not. Social media is necessary for democracy because it allows people to say what they feel. Democracy means that everyone gets a say.

According to Weston Gobar, “Social media can be good for democracy,” The Cavalier Daily, April 6, 2017, “Twitter has been a valuable tool for activist movements around the world.”
