Uruguay and Mexico Are Most Liberal Latin American Countries
According to a survey conducted in Latin American countries, Uruguay and Mexico are the most liberal countries in the region. Topics surveyed included abortion, euthanasia, homosexuality and gay marriage and legalization of drugs.
Mexico is not as liberal as it seems, many people in here have archaic thoughts regarding religion, sexuality, etc and the machismo is around the corner, however compared to many countries in South America it is very liberal.
Anyway this is just a poll, reality is more complex than asking a few people their opinions on five social issues. Mexico has its issues but so does Argentina.
