When labeling something as cultured or civilised, you are—for the most part—doing nothing but praising your [false] sense of “higher aesthetics”. What you don’t see is how you implicitly marginalised a large number of people and practices as uncultured or uncivilised.
The fact is that social phenomenon (whether linguistic or practical) are not inferior or superior, they are not civilised or uncivilised, they are just different. In the end, you are no one to silence or suppress an expression just because it differs from your perceived standards.
This is exactly what has made many a Punjabis in Pakistan consider their mother-language as inferior to Urdu. But it is important to know that this does not stop at languages at the larger scale.
