The other teacher is just being realistic. He's not wrong however there was probably a better way of handling things. I don't think he deserves the hate he is getting tbh.
Well that takes off the hate for the other teacher... A little? And a little note to the translator, it's best if you would've just capslocked it. Thanks though been waiting for a month for this
Translation wise, it is actually more or less fine in terms of word choice. The grammar is the only issue, which can be challenging. However this still flowed pretty well enough for a rough translation. Definitely not the worst I have seen by a long shot.
Honestly, an english speaking proofreader could likely fix this and it would be more or less fine since all of the important words are there.
