Sorry, I believe I misunderstood you. I thought you were _against_ granting the right of self-determination to Catalan people, that is, the people who lives in Catalonia whatever language they speak. I did not catch that you endorsed fighting for rights.
Just wanted to clarify that I do not particularly support all Catalan Government policies, in fact, just a few of them.
There are many important other rights that need to be addressed such as the right to die with dignity (this is long overdue) or the right receiving education in your language, at least for major languages such as Catalan, Spanish, Arabic or English.
Please note that this is not an issue only local to Barcelona, this is an issue that also face people who speak Catalan, English or Arabic at home and live, for example, in Madrid and only receive education in Spanish (is that also "uniform ethnic brainwash"!?).
My guess is that authorizities in Barcelona or Madrid do not grant this right as to avoid segregation, but we will not know unless they try it and see actual segregation. The other alternative of teaching everybody evenly in all significant languages in our society (Catalan, Spanish, Arabic and English) might overwhelm kids.
I'm not sure if you have any actual experience with the Catalan education system or just read about it on the yellow press and that build your opinion to define it "uniform etnic brainwash". Would you share if you have any actual experience with it and what impact it had on you or your children?
In my actual experience, my three children have been fully exposed to the "uniform ethnic brainwash" Catalan education and IMHO, their Spanish is better than their Catalan is, even when we speak Catalan at home. They have some knowledge of English, but they have no knowledge of Arabic.
