I don't agree with the anonymous email, but I believe the OP has a right to be concerned.
I am always astounded when people say "it's just English, it's not that important".
Language is what we use to communicate with each other.
We use it to describe our feelings, thoughts and ideas, and in the case of Bob Slydell when he posts "I could care less what grammar a math teacher is using" when what he actually means is "I COULDN'T care less", we use it incorrectly.
English is an ever changing language. As a result we have words like "bootylicious" and "truthiness" added to the dictionary. There are however rules to language just like there are to math. 2 + 2 will always equal 4. If you try to tell me 2 + 2 equals 5, you're wrong and I'll say so.
If you use an incorrect modifier or a dangling participle, guess what? You're wrong and I'll say so.
We constantly allow standards in our education system to be lowered. Don't believe me? Check out this story on CNN,

"
I've never seen anything that has been so much an issue in the community," said Arch Rodgers, principal of 670-student Kenton High School. "The worst part is this has drug out so long and the longer it drug out, the more it created friction in the community."
"Drug out so long and the longer it drug out"!!! This guy is a principal and he sounds like Cletus the Slack-Jawed Yokel. What chance do the students of this school have, to say nothing of the stupid behaviour of the two football players, when this guy is in charge?
How about the $2.13 million comma?

about how punctuation is an important and sometimes costly communication tool. I bet the folks at Rogers Communications Inc. wish somone had studied a little harder.
