Absolutely correct. Dear Sister.
We always get the best education in our own language and not in a foreign dialect. This is a proven fact and learning deen is an ultimate education, there fore it must be done in mother's tongue.
So called general arabic learners are neither good at it or really understand Quran, they just can't be, they just waste time. Quran is about understanding divine Laws, human rights, personal duties and humbleness. Without understanding them deeply result wont show and the result is every where. A religious chaos.
There are people who spent all their life in learning arabic like Dr. SA and in other nations too, but they are exceptions. Their work like Qxp is now the international lead, but its useless, if one keep it aside and start learning arabic from abc and try to become Dr. SA himself. The wheel has been invented. I dont have to be a medical doctor to treat myself. If i like Qxp, i will learn deen from it and my profession from a good college, univ.or whatever. But if some one want to be good in foreign languages, thats different. We all have our options.
Lets learn from good books, translations and let the school starters be good in their future professions, why waste many daily hours of their life for something they cant use. Early age is very valuable and it must not be wasted, but wastage muslim do not understand. Some members even argue that it is from God to learn from arabic only. I dont think so. How Chinese, mongols, westerners, african tribes or Japanese will learn from arabic, they just cant, may be in few thousand years evolution. But they can all do today in their own local language books.
I am sure if Prophet Mohammad(s) had live in France, then Quran would have been in french. Arabic is not a heavenly language, its a local language of arabic peninsula like any other language of the world.
Quality of translation and tafseers is a debatable subject and bad ones are automatically filtered out with time. My original point was that one can only learn deen in a native language, since brain is registered to understand things in that way from 0 to 5 years of age.
This could be a good book in this regard.
