He did not initially say anything to her. He was fine with a relationship, learned she has bipolar, and said that he immediately decided to not pursue a relationship and that he didn't tell her. It was awhile after that before he started saying he wasn't ready (which was a lie!)

And yes, there are always things people draw the line at. But drawing the line at a diagnosis, over behaviours/stereotypes that haven't been demonstrated by the individual? Nope. Not the same. He drew a line at one word: bipolar. He didn't draw the line over any behaviour or personality clashes, just simply the fact that she has bipolar disorder.

And he sure does have the right to learn - I've no issue with that. What I take issue with are people feeding in to his beliefs and supporting the stigma.
