Yeah, we just can't have people's feeling hurt.
Have you ever had someone say something to you and you did not understand what they said? Either a word of the entire sentence? You respond with something like, "What?" or "I'm sorry?" or "Pardon?" Then they say it again and you don't understand it again. Then you respond in kind, and for the third time you still don't understand them, and you say "I don't understand what you are saying." Then, finally, they manage to communicate in a manner that is understood.
In voice conversations when someone says something that doesn't make sense or cannot be understood, people point it out, one way or another. Nobody's feelings get hurt, generally. The same thing happens online, but it gets pointed out, people's widdle feewings get hurt, for no reason whatsoever. Mistakes happen all the time by nearly everyone when it comes to typing on the Internet, and you don't need perfect spelling and grammar, but the reality is if you want to communicate your ideas to others, then you need to do it in a way that actually communicates your ideas to others.
I make mistakes all the time, and many of them are typing mistakes that actually spell other words, so the spell checker doesn't pick it up. People are certainly free to point them out when they happen, because, duh, there it is. But to get mad at someone pointing out over-the-top pitiful grammar and spelling is kinda like following too closely and then the car in front of you slamming in their brakes, and then you getting mad at the driver of the car for slamming on their brakes. I found out a long time ago that the best way to prevent people from pointing out atrocious spelling and grammar is to not post things containing atrocious spelling and grammar.
