From whitewash (the paint) we got whitewashing (the covering up of misdeeds) and from there greenwashing, redwashing, bluewashing, purplewashing, pinkwashing - and now rainbow washing, where companies will put Pride flags all over products and posts during the month of June, but behind the scenes will not necessarily be useful - and sometimes they'll be anti-useful.

Mitra Kaboli, host of the new podcast Welcome to Provincetown, helps sort the real allyship from the rainbow-washing; and writer Sarah Schulman, who popularised the term 'pinkwashing', explains the more political meaning of the word.
