None of which detracts from the fact that National Socialism is an anti-Catholic political philosophy which must be resisted as firmly as Communism.
I wish somebody would explain to me what it was, because I can't tell. So far, the only thing that makes sense to me is that the nationalism part was a reaction to internationalism (what we're getting today with these "boundary-less countries) and the socialism was a reaction to capitalism, which was basically state sponsored usury (states enforcing usurious contracts) which we see some of the consequences or "punishments" of today, with bank bailouts, bankrupt governments and the people seeing their wealth bled out of them (working harder, for less money/your savings buying less and less).
I don't see anything wrong with nationalism. Although, it's my understanding that judaizers have cropped up in the past, who believed that their ethnic group was true israel and hence, only they had access to salvation. In that sense, they rejected catholic universalism and embraced Jєωιѕн exclusivism. But I don't see anybody doing that today, except maybe Jєωs, but I guess they always have.
There are folks who are basically atheists, who don't have much else to embrace, but race. Sure, o.k., maybe they sort of make an "idol" out of it, but no more so than a atheist might make a god out of money. Anyway, that's what zionism seems to be (basically atheistic Jєωs, with nothing but nationalism to cling to).
Socialism though, not much of a solution to state sponsored usury/capitalism. In a just economy, usury would be illegal and punished, not enforced and rewarded. Our trade policy, for example, would be designed to provide a family wage for the average working man (enough for him to provide for a wife and kids and still have time to take care of himself and spend time with them), not a trade policy designed to maximize profits for multinational corporations, with little to no regard for how it effects the workers.
