Don't believe there really is an absolute point of no return without the plot of Genesis of the Daleks happening. The future is long, and we don't know how the next four to eight years will play out, but dictatorships have risen and fallen before. Spain was a fascist dictatorship for decades, now it isn't. Also, lots of people died in the meantime and not all vestiges of the dictatorship are gone.
You need to have an opinion on everything that ever happened. Every forgotten Canadian drama series, every city in the Dominican Republic, every American football player. If you don't you are failing to appreciate the world in all its glory and will go to hell as a consequence.
