That depends on how you figure. Do you mean socially? Legally? Business-wise? There are a lot of complex forces at play to make Silicon Valley the way it is (including history). I don’t think it’s fair to tell any group not to “make” some city like their previous one. Furthermore, one nice thing about the American melting pot is everyone gets a voice. If enough people move to Texas and change its culture, that’s just something you have to deal with (or move, I suppose).
