the formal writing is for formal purpose.
so if it's a document for use as a contract, or specifications for a design or Request for proposal, there are very formal rules.
for speech, between people, that isn't written, one one accept that people use dialect. A 'stick to the rules' approach might be unfriendly. It's a kind of dominance game that some people play. They correct grammar when they really just should ask for clarification.
friendly people in discourse, when they misunderstand or are confused ask for clarity.
some people are grammar twits and correct grammer in casual conversation. That's annoying and controlling and know-it-all behavior.
the twits here who correct spelling and/or grammar rarely care what the anon is posting about. They merely want to put a gate in the way of a natural flow of ideas into posts to be used by the world.
in law, in contracts, and in formal writing for a specific purpose rules are necessary so that mistakes are minimized.
in discourse and informal speech, rules are useful to convey meaning. But if the meaning is unclear, in discourse through posts and speech, the recipient can and should ask for clarity if things are not understood. And ought to recognize the dialectical difference are not 'violations of rules of grammar'
I find that a plural pronoun is often used in a singular sense when the gender is not known, in speech. But in a formal paper presented to an English teacher it would be flagged as a grammar error.
