Please don't be snarky in HN comments and please omit personal swipes like "Once again, you are making things up." We're trying for curious conversation here.
Edit: we've had to ask you many times not to break the site guidelines. You've continued to make a habit of breaking them. I don't want to have to ban you so would you please fix this?
I'm not going to take my time to cover all of your points, I'm not using academic terms and yes, making up my own terms to put down what it's been my experience. Indo-European languages share a lot of structure and roots, similar ways of thinking even if phrasal structure are very different between Germanic and Latin languages, the same for Slavic ones.
I choose to do with my own time whatever I prefer, card tricks have been part of it, yoyo tricks in my childhood/teens, and so on. I'm not wasting years learning Swedish because I live in this country and I'm becoming a citizen, it's been a fun endeavour that I started with the mindset that in the worst case it'd be a party trick.
This is my experience, instead of being an ass, try to improve on top of it, you help nobody.
Now please, try to behave as is expected by the rules of this forum, I try to come here to have civil conversations and not expecting this place to devolve into some other cesspool subreddit.
