I'm not angry in any way. Perhaps it seemed to you because the manner of speech of Russian speakers can really seem rude and straightforward. In my answer, I mentioned why English is so bad, saying that I answered a similar question just below. In addition, I tried to answer each of your theses in the text so that there would be fewer such questions.
I thank you for the feedback and I repeat my words from the last post: if you notice any errors, flaws, bugs, etc., you can always let us know about it so that we fix it.
