In the old days of the Internet where everyone was pretty much anonymous you were exposed to a reality where anyone could prove you wrong. You spent a few years online you grew accustomed of the idea that there are people there much more knowledgeable than you. It didn’t bother you that much to be wrong because everyone is wrong on something and this shaped your tolerance. You enter the social media now and that tolerance goes out of the window because you can block people, delete their comments and reign supreme in your ignorance.
