Big difference between “for” and “at the behest of”?
I imagine the context in Rand’s writings had to do with her character stating the principles of economic freedom of one kind or another, and indeed that would be nothing to sacrifice for.
In Venner’s case we have a tragic loss of national identity; part of that loss, by the way, is occurring because of Man as image of God is replaced by Economic Man. That is, what he says, something requiring a sacrifice and he indeed sacrificed himself, demonstrably, on the altar of Christ. To tell him “go home, man, put the gun down, don’t you have a magazine to edit” is missing the point of this conversation completely.
If you can’t understand the difference in dedicating your life by choice to God or your fellow man, and being compelled into servitude to “another man,” then you won’t care to listen to me and I don’t care to listen to you.
Since you seem to be convinced that you alone have God on your side, I don’t suppose you will miss the company much.
