Of course it's an stupidity making a new Wikipedia
for a same language. But
at this moment, it's a fact that Valencian is not Catalonian, but there is a
lot of people saying that Valencian is the same as Catalonian. We, the true
valencian people (people who born in Valencia and has a huge legacy of
valencian parents), don't accept this term, because we know our real
history. We know facts such as when Joanot Martorell (a historic valencian
writer) wrote Tirant Lo Blanch many centuries ago, he said that he wrotes
the novel into "the beautiful and rich valencian language". Examples like
that, we have a lot. Is about those facts because we want to make our own
Wikipedia.
History is irrelevant. Two languages are the same if they express any
given idea with the same sequence of words. It doesn't matter if they
are used by completely different people with unique cultures, they are
still the same language.
