Yes, social media is more polarizing than community building. Recently, Tiktok has been extremely popular. The so-called "For You Page" on app, is personalized to each user. Due to this, social media can easily be more polarizing because these "echo chambers" are creating social media communities that are divided. People have their own opinions, and social media can easily enhance that. The more information that is released onto the internet, whether it is true or not, can change a users thinking. I found an article from Scientific American that discusses how "In a centralized echo chamber, if the influencer at the middle shows even a small amount of partisan bias, it can become amplified throughout the entire group." The article always states that "our country has been struggling with bias and polarization a long time" and is getting more and more urgent and evident as time goes on.
