For this reason, I think it will have more effect if your comments refrain from saying that "you're all deechers" and "if you work for shit schools you must be shit deechers", and instead suggest something that might actually make a difference.

Here's something that will make a difference: Don't go to China if these "schools" are the only option that you have! You are doing nothing but contributing to the emboldening of the criminals that run these kinds of places! But you did go, didn't you? Why the heck would you then talk like you're better than other posters for it?
