True. Articulate people appreciate seeing good grammar. They also, I imagine, enjoy hearing language spoken correctly.
However, I don't think you should take it as a personal burden to carry.
In many English-speaking countries, less focus is given to teaching grammar in school. I believe the US is one of the best in this regard.
Also, the internet has improved grammar in great ways, as grammatically incorrect posts get shunned immediately.
I believe it can only get better 
Something has been discouraging me lately. I have found that people have been brutally misusing apostrophies in the simplest of ways. Now, understandable if English is not someone's birth tongue, but for a native speaker? I'd venture to call it unacceptable.
Good:
I went grocery shopping earlier today. I bought some beans, some vegetables, and a Mothers' Day card for someone at work. I also bought some men's vitamins. It reminded me of the 1890s.
Bad:
I went grocery shopping earlier today. I bought some bean's, some vegetable's, and a Mother's Day card for someone at work. I also bought some mens' vitamin's. It reminded me of the 1890's.
The second version of my nonsensical scenario may seem absurd to some, but it is commonplace for these errors to be made. Now, I know we live in an age where colloquial speaking runs rampant through the English language, but this bothers me. I was especially sad when at a pool I went to, there was a bin that had a sign on it reading: Lost goggle's.
An apostrophie does not denote a plural. It sigifies posession.
Feel free to state your opinion's (sigh) on this manner. Please don't bother making negative comment's (sigh), those don't help anyone.
I'm no expert at proper writing but, "Bought a Mother's Day card" seems right to me. But if you said, "I bought Mothers' Day cards" plural, then it looks like it would be right having the apostrophe after the s.
Mother's Day is the official name of the holiday. It is for each family to celebrate its mother. Of course, grammatically speaking, it could be Mothers' Day (i.e., a day to celebrate all the mothers in the world). However, Mother's Day is the version used in the law which made the day an official holiday in the US, and this is used as a precedent.
Mother's Day is the official name of the holiday, but grammatically speaking, it could be both.
