that's simply wrong. There has been a lot of reporting of removal of babies from unmarried mothers. As well as reporting of the children stolen from the UK.
To say the removal of Aboriginal children was done as "the right thing for the children" is, at least, an uninformed comment. I know Aboriginal people who were removed and who weren't. None of the ones who grew up with their own families that I know, have committed suicide.

As usuual, the churches are big players in these atrocious activities.
