I know some democratic italian people telling stuff like l'africa comincia a napoli-Africa starts with napoli. For sardonia, maybe but what about venice?

Venitians third worlders? Laughable. First time I heard such stuff.

Second part is that quite often third worlders often already speak a common language used in democratic countries. Most of african migrants speak either english, french, german, portuguese, russian or arabic, all languages largely in use in democratic europe.

Migrants from south america already speak spanish when they go into the democratic us. So where is the problem?

Very different from the behaviour by democratic people who seldom learn the language of locals when they go into a foreign land -save china.

Hard to find a democratic one living in africa speaking an african language.
Hard to find a democratic one living in the democratic us speaking an indian language.

Yet fact is that venitians are limited in their use of their language by democratic people, not the savages.
