I still have some Ayn Rand books that I have yet to read. I am comfortable reading them as mental excursions, so long as I do not take them any farther than that.
Particularly subsidiarity is a Catholic concept. And the values of it does not by its own merits interfere with moral understanding. However, within individual minds, the concept can become faulty and deranged. This is one of the core issues between Republicans and Democrats within the US. Republicans do not with to abolish federal autherity nor do the Democrats wish to remove state individuality and soverign. However, they vie for power between the two systems as if they polarities and argue subjectively about the balance of power. The pure teachings of subsidiarity is not subjective, it is objective. There is a balance. The individual situations will call for different balances, but the balance itself is true and effective. This is my understand and interpretation of subsidiarity.

Personally for me, solidarity is a human trait and solidarity movements are manifestations of that innate desire to commune with each other. Since I am referring to a non tangible concept and can only relate to it on an individual basis, subjective views of individual solidarity movements are beyond my grasp.

I support you on your values. Having morals, values, and a searching mind are all virtues in my humble opinion.
Edit: As I stated in a previous post, I do not subscribe to Objectivism. This edit is here in case anyone did not read my previous posts on this topic would be between page 20-22.
