HAPPY BIRTHDAY JAMES POTTER, PRONGS, HARRY'S DAD, SIRIUS AND REMUS BEST FRIEND, LILY'S HUSBAND, GRYFFINDOR'S CHASER!!!
I personally think James Potter was a great guy. The fantastic thing about the characters in Harry Potter is that all of them are real, not perfect and have their share of flaws. In fact, up until the point that we read about Snape's memory of him being bullied by James, I'm pretty certain most of us looked at James as a good person.
And that's the biggest problem. There's literally just one chapter that discusses this bullying episode briefly, and many people jump on that alone.
