I'm not necessarily disagreeing with you, as I myself could have gone the disgruntled route. I was the youngest director elected to the temple I attended in 2006 (the same temple my father was the founding President of).
I served in that role until 2016 when I was voted out (along with my father) by the same temple congregation. This entire story could warrant a novel on intergenerational dynamics, Hindu traditions, and a whole slew of other topics (I was also involved in a lawsuit as a result of this entire ordeal.. Story for another day)
The problem I do see, however, is an apathy among 2nd Gen to take action. Laying blame is not going to solve anything.
I chose another route. Being voted out freed me to focus on teaching classes at temple and being everything to the next generation that I never had—the person they could approach with questions, the person they could debate with, etc.
It's also brought me to YouTube and social media, among other things.
We can't just criticize from the sidelines—2nd Gen need to get moving and quite literally be the change they want to see (sorry for the cliché).
that's good if some do, but its certainly not the average temple, and its not what we see in the zeitgeist.
There is a reason that every pro-H ABCD is disgruntled, and citing your temple doesnt mean that the average temple suddenly is churning out based Hindus.
