Not only are you overreacting, but also mistaken.
If people supply something with a typo (as in the previous post), that can easily be corrected. What is more difficult to correct is people’s misconceptions. And there are lots of misconceptions round here, believe me! One learns more by exposing misconceptions and having them challenged than by hiding them because one is not 100% sure. Far better to have the misconceptions here than in some piece of code where they can do real harm.
