Householder David Lewis, interested,
be clear that you ask that here in a community that has spring from such movement here, void of those who follow the Buddha straight in all aspects.
The modern Vipassanā Movement has actually less to do with the Buddhas heritage as it has actually mostly no refuge in what is headed toward Nibbana as object but merely how to avoid suffering while still desire wandering on in the world.
Modern Vipassanā Movement came up with the decay of traditions and got inspirations for "positive" Marxist tendencies arriving at the same time those western or European modern ideal had destructed all traditional countries at their substance, leading them toward socialism, communism and democracy of which both are based on denying superiors and higher but seek refuge in cutting things down to the lowest equal.
Modern Vipassanā Movement lack not only respect as one of the main bases, but also generosity and so is at large just a huge Dhamma-industry with less success in leading people on the Buddhas Path but simply back in their homes.
As third basic lack it misses the need of virtue in patient since it is something traded similar as booking holidays or give into quick treatment.
All of that is a sign of the main basic quality of which is confidence which of cause is also a matter of lacking of touch. After the big wars on this earth some thought that they are compassionate by turning away for the Buddhas religion and started to give into alternative movements, but those movements have no, out of reason, real blessing by the founder of the original movement which is designed to escape world and suffering.
To understand the different between accessing the Noble Domain or just another household and alternative trade, the essay Respect, Confidence and Patient and Better to Give than to Consume might be of help for those with lasting Upanissaya toward the Noble Domain.
It's very very seldom that even after many years and retreats people of this movement actually turn to refuge, perceiving the Tripple Gems right and hardly ever would someone having found refuge turn toward such outwardly movements.
