Not neccessarily, for example, in Russian, a double-negative is not only common, it is proper.

That "grammar" exists is many different languages, and of the Americans who complain about the use of bad grammar, I wonder how many of them have perfect grammar in at least one other language . . . . Culture-centricity is another form of narrow-mindedness, if you ask me. But most have not bothered to allow that thought to run through their mind. When I speak to my Russian friends, I do not have them constantly correcting my grammar, when I speak to my Spanish friends, I do not constantly have them correcting my grammar . . . only in America do we seem to have that language-centric culture-centric bias.

@THHA i am dyslexic and hate being corrected

@Athena thank you I say what I think xx

Most of the things I read I make mental note of the fact that I may misinterpret it, because there is far more to it than just grammar, miscommunication is prevalent. Every word each of us use is a potential misunderstanding . . . . for example, without looking at a dictionary, how would you define "prevalent"? Now think about how someone else might define "prevalent", or maybe an even more abstract word . . . . well, each word has that potential, the potential that we may each have different ideas of what it means, what its definition is, what emotional content we attach to it, and what in means in context with other words. It is easy to adopt the notion that we "understand" each other, but in fact, it is a joke to think it is possible to do so to a great deal of certainty, unless you are talking about mathematics or formal logic, and even that is questionable at times. Grammar is a drop in the bucket when it comes to "understanding" what is said, put in that context.
