I used to be like this, but it was a social anxiety thing. People say wrong and insulting things all the time without loosing friends. The key is keeping an open mind and being willing to admit when you’re wrong. If your intentions weren’t to cause harm, most people will forgive your faux pas.
Came here to say this. They make a joke about how many adds are on the Internet in an episode of Futurama that aired in 2000.
