If the piece by Brinda is indicative of the extent of interest and involvement of our children in our culture, it is definitely encouraging.  But unfortunately such can not be generally said, our so called second generation is not into Durga Puja and sundry other Bengali cultural stuff. I am pleasantly surprised and indeed gratified that one of the members of that generation keeps track of the Bengali socio-cultural scene and takes part in it.
Her opinion and her article, articulate, lucid, thoughtful and most of all respectful, deserves attention and should engender steps to address her concerns. If we mean what we profess about the second generation's participation, we better not ignore her.
But I recognize that there may be a cultural communication problem too. The standard of decency and decorum of the likes of Renee and Brida who have grown up in thia country may be in clash with the one and a half generational internet crowd's. The perceived rudeness and the lack of propriety may quite be acceptable and common place with the environment they grew up in.
Brinda, you are an excellent dancer and performer, we all have taken notice of you since you're a child. But, you know what? You write well too, you should do it more often, about Bengaliness of your generation and your views  about our heritage. Sudipta Bhowmik offers a great vehicle for expressing yourself.
