Spiritual crisis, when true, always presents itself as an individual manifestation, and not as a collective phenomenon. This is per any definition of a tangible, discrete soul.
I think that the two are not mutually exclusive. Otherwise we would not speak in general terms of social, political, economic and/or religious crisis as the one we are living in the whole planet. It affects us all, but it is only the way in which it does so and why that is different. That is the individual part.
But nothing prevents individual paths to cross and find common ground and similar problems and concerns. Also if you are already familiar with the content of the forum, I guess you are aware that there are group souls and they share similarities. Add to that, that the soul is supposed to be multidimensional in nature and could be in multiple realities that affect each other.
