In principle I agree with you, pacific discussion and democracy should be the way to go. But it seems that "discussion" doesn't lead anywhere these times. Politicians do whatever they like (or what lobbies tell them to do), without checking if the majority of the population really agree with some decisions. A developer does whatever he likes, without bothering about the more or less pacific feedback he gets on github. Nobody really seems to want to have a discussion. Well guess then what the "mob" does at some point: they don't care about discussions anymore either, and they do as they please too.
I fear that riots will start on a larger scale. Even if the context today is different, the situation reminds me somewhat of what happened with the 1981 riots in Toxteth, in Brixton, and other previous riots. Unjust or misused laws; deafness of authorities about discontent; innocent and not-so-innocent people getting hurt.
