It comes from the fact that when you say anything incorrect online, there's an infinite number of people who will call you out on it. Your intellect is always on trial. You have to convince a jury of the entire planet that your opinion is valid.

Take the same comment or opinion and air it among three friends in person (or a very tight social network). You only need to convince two or three people who likely trust and respect you already, and who are not inclined to want to spend an infinite number of hours debating such trivia across all time zones.

Why not just engage in conversations on the principle of charity and good faith. There's also the concept of steel manning other peoples arguments to help extend good faith.

Not every conversation has to become a burned bridges and salt the earth affair. If the other person is just trying to "win" then disengage from the argument. If the other person is arguing with you in good faith then maybe you're wrong or have something to learn from a new perspective.

But... an infinite number of people aren't reading every page on the web, all the time. Even on Reddit, you're only really interacting with the limited subset of users who choose to comment, out of the limited subset who read a thread - which is still possibly bigger than a circle of friends, but smaller than any significant fraction of the human population.

There is the perception that "the entire world" is watching you on the web, criticizing your every move, but that's not a fact.
