Unfortunately, I believe that social media does influence people’s decisions very much. If that weren’t the case, criminals like Trump could never be elected president, and 20-25% of the people in my home country wouldn’t vote for open Nazis.

Nevertheless, thank you for your valuable contribution: In addition to technical possibilities, I am also interested in how to deal with people who do not accept rational arguments - the Socratic method is probably the best way to make a point with them.
