Esperanto is eurocentric, because it’s international. Because romance languages where made by colonialism of the roman empire. The argument goes of “equality”. Thinking the other way around would be that asiatic languages colonized the world, then Esperanto would be based on asiatic languages.
Esperanto is a pragmatic language, not a “totally neutral” language. If you design a language to be “totally neutral” then parts would be distributed differently. How to chose which vocabulary of languages should be used often?
So using romance languages is a pragmatic solution to this. Through usage words can be added or fall out of use, all that is allowed in Esperanto and which can make the language out of colonialism in the future more egalitarian.
But it’s ignorant to ignore Esperanto at all and morally vilifying it as “eurocentric therefore bad”.
Every book is not “accessible”, when it’s not even opened and willfully ignored of existing.
There is:
There are languages to which it’s less accessible, but from the bigger ones, it’s quiet accessible.
But if people don’t open their eyes they don’t see the forest in which they are standing.
