I come from a town where I regularly heard and saw cultural things like those—plus phrases and food from Irish, Polish, and Italians. I was one of few “Old New England Protestants” among my friends and classmates.
The culture of the 70’s was certainly more open about picking up African American mannerisms through music and movies.
I am thinking we will see a shift towards more influence from Hispanic culture before we die.
It’s just the way of this world.
But I agree that “proper English” should still be the language of business and government. It drives me nuts to hear people that are third generation “American” and they still speak Spanglish or heavily accented English. There is no excuse for there not being a common spoken language.
The media pushed everything black as dominant and hip starting in the late 60s, it really degraded America and was really trashy in the Army, and every young male and dad was pushing it onto their little kids.
