I've always been puzzled by the idea of personal heroes so it is possible that my inability to grasp the concept of a hero is part of the problem here.

I've noticed that, even if it may be a worthwhile endeavor, it doesn't help so much when you present the names to other people. Every time I've done so, I've been challenged by similar disagreements, and it becomes difficult for me to express why I consider them to be useful role models.

My suggestion to you is not to update. If I could take the whole thread back, I would. Consider me updated to 'personal heroes should remain personal,' and 'this post is not a call for personal heroes, but for easily remarked upon examples of rationality in the real world.'
