I don’t know the specifics of US policy, so I can’t respond to that, but his general point certainly seems to match what I have seen in some of my circles. Ironically, at the same time as I have seen people hold newcomers to an unreasonably high bar, I have also seen them treated (sometimes by the same people) with an unusually low bar. For example, insisting that the newcomers house should only be set up with old, leftover bedding etc that others are finished with because “they are newcomers and it’s good enough for them… they shouldn’t be picky… etc etc.” Fortunately, those have been the exception in my experience – the norm has been to see newcomers welcomed with love and go on to do great things, with nobody expecting perfection, the same expectations we have for everyone else. 🙂
