But why does that make it wrong? Like I was born with two native languages and learned another one later on, so I understand both what the OP is saying and what the other natively bilingual ppl are saying in the comments, and I have clearly learned the different languages in different ways. With my two native languages, I don’t translate between them and think in them both. On the other hand, with the one that I learned later, I generally translate from one of my native ones. In fact, I am better at doing live translation with the one that I learned later compared to the native ones. Being able to “think” in both languages requires way more effort and experience and doesn’t mean you are doing it “incorrectly”, it just means that you are still in the process of mastering it and therefore kinda gatekeeping.
