Actually, this isn’t true - it has been done, and it has worked. In 1814, a law was introduced in Paraguay which forced inter-racial marriage - it was illegal to marry someone of the same race. This forced those of European descent, and those of indigenous decent to “come together” (pardon the  risqué pun) and ensured that the vast majority of future generations would be mixed-race, known as “Mestizo”. Today, more than 90% of Paraguayans have both European and indigenous ancestry; both indigenous Guaraní language and Spanish are spoken widely, both indigenous and European culture is lived and celebrated, and the innate acceptance of other races and cultures has led to a very large percentage of Paraguayans having a non-Paraguayan ancestor or relative, as well as a culture that actively welcomes peace-loving foreigners who come to the country. Maybe it’s time for you to experience Paraguay for yourself - but please leave your pre-conceived biases at home when you travel somewhere new ❤️ #paraguay #asuncion #multiculturalism
