There was no such thing as "colonization".  Just because one group immigrates earlier to a region, does not give them special rights.   You are using the exact same kind of flawed logic that racist white people use, in complaining about current immigration from south of our border taking over parts of our country.

They also think that because they were here first, that they have special rights over more recent immigrants.  It is the exact same kind of thinking that you are engaging in here.
