Americans don’t memorize all that shit for English either.

... because it doesn't exist in English. Of course you don't remember things that don't exist.

Don’t try and learn it out of a textbook, just start talking and reading.

Yep. That's why you can pick out every American stumbling through German even after they spent 20 years in the country, because they can't get any of the things that you have to memorize right.

And the best part is you can pronounce their words pretty logically.

If you think that what they teach in American schools in German, then maybe. But seriously, pronunciation is so not the hardest part about learning languages.

And as I said, German isn't even a hard language either. That goes to e.g. Finnish or Hungarian (at least for western languages). But English is an easy mode language.

What the fuck do you think learning vocabulary by reading is, if not memorization? You're just doing it subconsciously rather than intentionally.
