Just because I don't agree with your opinion doesn't make me rude or unpleasant. I suppose my first comment may appear rude if you are not familiar with the joke. Also, if you wish to stop engaging with a person, then consider not replying at length, and then doing what's pretty much putting your fingers in your ears. I'll give my piece regardless, as this is not a private forum and I'm allowed to write. Feel free to block me though.

Firstly: you calling a well written post as pretty much useless (not helpful) was rude from my pov. And one that's filed under a thread, on a shitposting board of all places. For one reason or another, you saw no value in a post, but 50 others did. International Phonetic Alphabet is familiar to most non-native English speakers, so maybe the discrepancy comes from native speakers being confused, and rest of the world not? Idk, but I found your negativity towards the very informative comment weird, and the accusation that it was not explained in layman's terms weird (because that's what his last paragraph was). There's only so far you can dumb things down, some effort and base knowledge from the student is required.

Hot take: Perhaps you were simply that one kid in a huge class that didn't get what this teacher told? Comparing a random comment in a Lemmy to someone doing a job they are being paid to do is downright weird, as if they were somehow required to hit the same level of professionality. I kind of figure that we might hail from countries with very different schooling systems. Where I'm from,. students are expected to work, Tom understand, so that the information sticks better as you were more engaged, rather than getting perfectly chewed up info to begin with.
