I think she represented the modern manifestation of Christianity pretty well, a whole lot of Christians have things completely backwards & she is not wrong to point that out. But her heroes were actually very Christ like. Married to truth & to making the world better while being persecuted for it. So her efforts to communicate right from wrong are very in line with what Christianity is supposed to be.

Her attack on Robinhood is similar, she even points out that he was actually robbing royalty & tax collectors to return things to their rightful owners, but it's the incorrect surviving ledgend in the minds of men that Ragnar is fighting.

She didn't in any way suggest that big business was opposed to regulation, her bad guys were people with big businesses using regulations to get ahead. That's like the whole story.

As someone who has read Atlas many times (& I get something from it every time) I would suggest that you might need to give it another go with fresh eyes.

I like Anthem, but The Fountainhead honestly didn't do that much for me. I do appreciate the points about authenticity tho.
