So by all means explain to me how I'm being overly simplistic (because I feel that I am), but while our brains like to ponder the complexities of this situation, can't we at least conclude that it's a bad thing that physical, state-backed violence is used to prevent people from doing something that isn't in any way physically violent (and in fact a rather admired 'action') in itself? I mean, hell, it's quite possible that even if an overwhelming majority of Catalonians vote for secession (which I hear is not even likely to be the case?), reality will get in the way. At the very least even the worst-case scenario, in my opinion, does not justify physical interference in a non-violent process. But again, honestly please correct me if I'm missing something blindingly obvious.
