Frankly, I think Berzin's "dharma lite" is a humourous attempt at describing a certain approach to the dharma.
Unfortunately, this humour is not seen by those who are obstinately attached to their views.
What is more, dharma lite applies to students who simply leave out certain aspects of the dharma.
It does not apply to students who actively skew, distort, and redefine the dharma to fit their own terms.
The latter is not dharma lite anymore, but more in the way of quack dharma.
There is a big difference between dharma lite and quack dharma.
The first could be described as an eclectic/agnostic approach, an approach that can be considered stepping stones.
The second approach, quack dharma, cannot be considered stepping stones, for obvious reasons.
After all, dharma lite is fairly innocuous compared to quack dharma.
