You really do need to read the available research that deals with this act of "cultural genocide".  We are connected to the land, the water, and all our natural relations.  Do some reading on blood memory.  It is real.

I am one of those "they didn't so much lose it as became separated from it.
And those who were taken very young would not have formed a cultural identity to lose."

Your opinion is just that and differs from the available research and from my personal experience of being separated at a very young age.

I have said many time settler need to stop commenting on Indigenous issues until they have listed deeply and studied extensively.  Our world is totally different than yours (Thank goodness)
