Rand's philosophy of "I Am A Beautiful, Unique Snowflake" (or Objectivism, if you want to sound stuffy about it) goes a little something like this:
The Fountainhead's main man/Objectivist mouthpiece Roark does all these things. So you can base your allegiance to Objectivism on where you think Roark falls on the "dirtbag to superhero" spectrum.
Dominique has her fair share of issues, but ultimately she's a bold individual who stands on par with Roark himself.
Dominique isn't a brave individual; instead she's someone who acts out of fear and ends up conforming to society even as she supposedly revolts against it.
