Farhod, браво!

Farthead, remove that stupid response.

We remind you, however, that quite aside from all your theoretical knowledge, you need to follow your primary's advice.

Thank you, Grumbler!

Стоит сказать, что "при всей теоретической осведомлённости" - в какой-то степени ироничное выражение - знаем мы вас умников, начитались всяких книг и интернета и думаете, что вы теперь все знаете.

Aга! Буду знать! "We're onto you eggheads! You've read heaps of books and online resources and now you think you're the end all be all."

I think the boys need your help - they just don't get it: https://www.lingvolive.com/en-us/community/posts/1014945

Of course, you are too idiomatic

It's not too idiomatic, that's how we talk. This is something you can hear in a normal conversation.

Additionally, if we made everything simple, what would be the point of learning? There's nothing wrong with a little challenge as long as it's valid and useful. No?

It was just an explanation, not an accusation.

No sweat
