Atlas Shrugged (and the fountainhead) is like a superhero comic book where the almighty good guys fight the flat, faceless "bad guys" with pure and fully justified moral righteousness. The "bad guys" are a slobbering caricature of a boogeyman that everyone can easily despise - wanting to do nothing except take from others like a bridge troll or a grey goo disaster scenario.

Nothing wrong with that I suppose but the second someone implies it has something to say about real life capitalists or social welfare or anything else then it gets weird; that makes as much sense as any of the marvel movies helping you decide how to vote for exactly the same reason.

I expect it's for this reason you're being downvoted - these books are often used as a motte and baily to imply something about real life (or often to ironically excuse their own selfish/bad behavior) and they just don't hold up for that in my opinion.

Probably because the author was an insufferable person and that that very book was part of the basis for (not "twisted") her inhumane and pretentious pseudo-philosophical spin on libertarianism?
