From my trip there in 2012 I found the islanders very warm and welcome. There was no "xenophobia" that the wikipedia article states is an impeding factor for immigration. There is no evidence or cite given for this statement and it seems intended to discourage people from having a positive view of Pitcairn. This section of the wikipedia page was originally written by wikipedia user JBarta
Please don't use the negative press as your main source of information about Pitcairn. Consider visiting the island as a tourist and spending some time there. Reach out to islanders via email or contact from their websites. For information on immigrating to Pitcairn Island there is a FAQPitcairn ImmigrationRepopulation Plan (PDF)
If there are any other sites that provide online ordering of Pitcairn items where the funds go to the island please get in touch via chris@pitcairnnews.co.nz
