90% of the time I see grammar nazis doing their thing, it's never about protecting the "sanctity" of grammar - it's more about exerting control and attempting to enjoy the feeling of being right.

The other 10% of the time are from people that know its purpose is to be a vehicle for communication of ideas, and will also make up statistics.

Yep, all good. Though in no way was I being a grammar Nazi, I was stating my opinion. I don’t bother with perfect punctuation because it’s not necessary to be instantly readable.

Also, my nephew told me that putting a full stop at the end of a sentence now is sometimes seen as a bit rude 😅 No idea why, but that’s ok, it’s still just as readable

Yeah, I heard mention about periods at the end of chat, comments, and txts make them seem more rude since it's supposed to be a more informal form of communication. I take it as them interpreting it as the sender being overly formal and strict, and the writer dictating, as they're reading it in their mind, where the end of the message is.

Instead of letting them read it with an open invitation for a reply at the end, it communicates the sender doesn't want to continue further down the topic; it's definitely something in language that's part of a generational divide formed completely by the media it's being conveyed in.

Did an internet search after hearing it, and came across articles that bring it up; like https://www.npr.org/2020/09/05/909969004/before-texting-your-kid-make-sure-to-double-check-your-punctuation
