Although many of its supporters argue that there is overwhelming momentum towards independence in Catalonia, there is no evidence for these claims. Many Catalans complain they are the silent majority who regard themselves as Spanish and do not want to break with Madrid.
Catalonia has been a part of Spain since Spain became a united country in the 15th century, and was an integral part of the unification of Spain under the crown of Aragon. It is not a historically occupied territory and has never been an independent nation, but has been a key region in Spanish history.
It is irresponsible to support divisive nationalism. Europe and Spain are stronger through their diversity. The unity of different cultures and peoples is something to be celebrated, not feared. Spain has many diverse regions and unique local cultures, and Catalonia is among them.
There is a strong undercurrent of xenophobia in Catalan nationalism, which challenges modern ideals regarding diversity.
Spain is at risk of unhealthy Balkanization in which regional resentment is encouraged. Many European leaders have argued that to allow Catalonia to separate would set a dangerous precedence and inspire hundreds of tiny groups of extremists to follow suit. Additionally, Catalan President Quim Torra, a pro-independence leader, has been accused of racism and prejudice.
The celebration of unity, and not division, is a necessary component of democracy. Many Catalans still feel Spanish, and Catalonia is a historically significant part of unified Spain. It would be needlessly divisive to place an arbitrary divide among the residents of Spain.
