You said: "Providing basic Quranic education is the responsibility of Muslims & Tableeghi Jamaat."
When the the Thableegi Jama'ath - today's most popular and most widespread religious organization in the world - blatantly refuses to give primacy to Al Qur'an in their mission, and when the Ulema give primary importance to other sources, who is going to take the responsibility of at least reading out a mere translation of the Book, to school children in the class room, if not those who think (like that school manager) that Muslims believe in the primacy of Al Qur'an, ? After all, he who reads it to others, will be the first to ponder over it.
You see, the parents could not even give the school manager a good chance to ponder over Al Qur'an.
Yes, and not without reason. The more a so called non Muslim reads and ponders over Al Qur'an, the more he will perceive how much far removed from Al Qur'an today's Muslims are.
This attitude of today's Muslims is akin to the attitude of the people of the Book, who used to warn one another against revealing the truth in the Torah to the Sahaba of Prophet Muhammed, lest the Sahaba get a fair evidence against the Jews' refusal to accept the truth in both precept and practice. (See 2:76)
We know only to retort at such a kind and great gesture proudly saying, "our children read the Qur'an at home anyway". But the whole world knows that we read, if at all we do, without pondering over it's meaning. We will suffer in both the worlds for repulsing a great gesture.
I think, in today's world, there is not much in a name, for us to be prejudiced against.
