In linguistics, nearly all researchers ascribe to a worldview known as descriptivism. Since language is constantly changing (in space, time, and by in-groups, such as race), it is impossible to choose a single correct way of speaking for everyone, and doing so has often been used to justify racism.
All these grammar nazi types basically only accept that the language they learned is exactly correct at the time they learned it, where they learned it. Any deviation from themselves is not normal, and wrong, even though scientifically, languages are constantly evolving, and thus to see what speaking correctly means, we must see what most people agree on or use to communicate. Nobody writes to-day anymore, but just over 50 years ago, that was correct.
