Over the past few years, I have heard from many wise people that the social development of our society has not kept up with technological progress. That is, in some moments of our lives, we still haven't moved far from people of the Middle Ages - only now we have smartphones and social media... All this concerns our susceptibility to various superstitions or completely unfounded hatred of something or someone.
After all, if you think about it, there's nothing bad about the objects we dislike. For example, how stupid does it seem to dislike the opposite side of a sports rivalry, right? (Okay, this is written by a Cowboys fan who was incredibly upset when the Eagles won the Super Bowl...)
