In my opinion, online bubbles play the biggest role that people have an established opinion, which then turns into hatred for dissenters. When search engines, online platforms & Co always only show posts that represent similar opinions, individuals often no longer have an awareness that they belong to a minority and thus do not hold a general opinion. With today’s technology, it must be possible to filter out the opinions and not allow it as a criterion for the next article/search result/video.... If an online service believes that it cannot do that, it should be obliged to completely eliminate these algorithms – this would also force large companies to act.
