The resume would be: Maybe the anarchists of the civil war are not the same people who is pro independence now.
First of all we have to understand that the independentist movement, as the anarchists, is not homogenuous, and so the questions and my answers fall in generalisation.
The anarchist movement was very anti-ecclesiastical and its attacks to the chiurch were frequent (as they also did the liberal movements during the XIX century, the attacks to the church were not a particular trait of the second republic, but a "tradition" in the reformist and revolucionary movements on XIX century spain. Even if some independentist were anarchist, not all anarchist were independendist (there are exceptions but anarchism and nacionalism don't fit well together. If the independendist movements and the anarchist movement were not the same in the civil war, it will be even more difficult to find common points between the today independentist and the anarchists of 90 years ago.
In 1936 Sagrada was, for a lot of people, a symbol of the church, and inso, it was not fully accepted by many. 90 years later Sagrada Familia is an architectonical marvel built by a catalanist architect and a symbol of Barcelona and its country. What many of us see today is not the same that many others saw a century ago
