Maybe he said it that way on purpose attempting to use the ever-so popular art of sarcasm via the internet, which tends to not go over well do to lack of voice-changing via text.
I see that English classes in the public school system has taught you well.
Oh, what an unfortunate and unwittingly comical time for a poorly written sentence.
If someone is going to point out someone else's poor use of English, that person should pay due attention to their own use of English.
The quoted sentence above, properly written, would be either, "I see that English classes in the public school system have taught you well," or, conversely, "I see that English class in the public school system has taught you well."
Rate me down. I don't care. It had do be done! *Mwahahahaha!*

Oh, come now. This use of "their" did used to be verboten, but with time, as we've tried to write in a less stuffy way and sound less prudish, it's come about that we don't have to write "his or her" anymore. Sometimes that's necessary, but it wasn't in this case. It's not considered absolutely proper, but it isn't necessarily incorrect every time. You couldn't get away with it in a high school paper, but beyond that, it's become not so frowned upon, even in academia.
