Yes old school. I appreciate your point . Dominicans do not speak good spanish .. I would also think that si Dios LO quiere would be more correct. I have been to Colombia many times and can not recall hearing Si Dios quiere o si Dios permite ever.
What is Good Spanish ? I am of the opinion that any language you speak Spanish, English French etc. will have different accents and dialects depending on where you live in the world and Dominicans speak Caribbean Spanish with there own flare.
Because you weren't educated in England and don't speak like them is your English bad
Because you weren't educated in France and don't speak like them is your French is bad
Because you weren't educated in Spain and don't speak like them is your Spanish is bad
I would say not bad just different.....but being that I was born in the Western Hemisphere from Italian and Spanish roots I speak the way I speak because it's what I was surrounded by, so how I speak ( in whatever language I am speaking ) is good by me as long as you can understand me.
This is not meant as an insult to the quoted post by the way just an observation
