[Marvel / DC] Why is Batman so reclusive and secretive about his alter ego, yet, Ironman is the total opposite.

I am in no way a Marvel/DC/comic book buff, I am just curious of the answer, is there an answer in their back stories?? They both appear to have very similar lives when not being a superhero.

Batman's origin came from a dark place. He saw his parents gunned down in a back alley, took inspiration from his terror of bats, and created Batman to strike fear into the hearts of criminals. In essence, he became reclusive and secretive because the people he tangle with could go after those he cares about, such as Alfred or Robin. He knows that criminals are willing to kill them because of him, and so Batman doesn't give them a chance to find out who he is.

Conversely, Iron Man arose from his own ingenuity, and converted himself from a playboy to a superhero rather than a playboy with a dark past like Bruce Wayne. Tony also doesn't really have many people he cares about, and those who he does care for are often super powered and can handle themselves. Therefore, Tony can confidently revel in the popularity of Iron Man without fear of his friends and family being compromised, whereas Batman has reason to fear for his own friends' lives.
