No Equal Opportunity in Guatemala

There is no such thing as equal opportunity in Guatemala. It appears lawful to discriminate on the basis of gender, age and religious preference. While looking through the Prensa Libre´s monday classifieds, I came across a job postings that included the following requirements:

- Arquitecta (sexo F)

- Piloto: hombres entre 18 y 35 años de edad

- Cristiano evangelico

I wonder if it is ok to discriminate on the basis of race, but they just don´t include it in job postings. It must be ok to discriminate against pregnant and unmarried women. I wonder if this is true in all of Latin America.
