Everyone Is Required To Communicate In English
The wonderful thing about having access to the internet is that it enables one to become familiar with people, languages, and cultures from all over the world. Platforms such as YouTube allow even people who do not have the financial means to travel to be able to experience various cultures and learn new languages.
People like this one, who insist that others adjust their behavior to accommodate their preferences, are one of the drawbacks of the internet. They have the option of downloading a translation or reading literally millions of tweets sent by people who speak English if they are unable to read German.
