Portugese would be a good language, theres about 97 million "whites" (branco) in Brazil (those that identify as white, so take that with a grain of salt) and probably about 9 million in Portugal, that's over 100 million "whites" that aren't being redpilled by the DS, plus you've got the browns (Padros) that I think could also be redpilled (strong family values, Catholics, generally dislike Jews and niggers)
