Esperanto does not need Native speaker.

 

How many linguists dare to change the concept about language ?

I afraid none of them dare to challenge the tradition of saying language is the belonging to a tribal issue.

They do not look into the issue of second language and first language or even the mother tongue, born to hear the sound.

Only those coming from the monolingual background especially from the USA, Britain, Australia are more prone to the toxin of the language theory. Of course, in the countries mentioned above, there are local people, or so called native speakers, like Indian and aboriginal people.

This is the internet age and if you were still harping on native speaker of a language, you were out of the language world. If you were pursuing for a paper, degree in this case, stood up and defence your view of point in the linguistic world.

Esperanto is never created to be the native language for anyone, it is created for second language. Its main focus is for easy learning.

If the Esperantujo were still sleeping and arguing for it and bring out many Esperanto native speakers, they are as silly as a goose. 

The Esperantujo is fulled of language lovers and these people do not feel the needs to make Esperanto to eradicate the illiteracy in the world.

Only those who know nothing about language would talk about native speaker of a language and language related culture.

If one person spoke 10 languages, is this person knowing the 10 cultures of those languages? Each human being if were given a chance, they could easily speak more than 5 languages.

Europe or USA is neither a monolingual place nor in Latin America. It is the short sighted of linguists that make the whole issue of language studies become a bias. 

Stop comparing all languages as native speakers own. Do you agree with Darwin theory of human evolution ? Where did the human being come from ? In short all languages are made and none of the language is borne naturally. Of course, stop using the term, natural language. 

The conclusion, Esperanto is a second language for those who like it, Esperanto does not require to have native speaker.

Need a change in the definition in Wikipedia ?

Some children learn more than one language from birth or from a very young age then they are bilingual or multilingual. These children can be said to have two, three or more mother tongues: neither language is foreign to that child, even if one language is a foreign language for the vast majority of people in the child's birth country.
