Is it time to start calling out bad cyclists?

I feel a little bit ashamed of berating a lady so much that she chose to ride a different route home to avoid me, but she almost killed me and refused to believe she was in the wrong. I was filtering on the outside of traffic, she was on the inside. She decided to go between cars to go on the outside without looking. It was a choice between us two colliding and probably falling into some cars, or being hit by oncoming traffic by swerving around her. Luckily the oncoming car jinked left, anticipating my reaction so I managed to get out of the situation unscathed but my reaction when it happened was to scream and swear. Not to offend or be aggressive but it was just a reaction to what I thought was about to happen. I'd managed to slow to walking pace while swerving around her and I heard her shout out, "No need to shout at me!" I looked back and she was giving me a really dirty look. I was ready to just ride off, content in the knowledge I'd had a lucky escape, but her nonchalance at the fact she'd almost got me hit head on by a car really pissed me off. When I told her she had almost got me killed by an oncoming car, she told me it wasn't her problem and that it was my fault. When I asked if she'd considered looking before just wobbling out between cars she rolled her eyes and told me to leave because she didn't want to enter into a conversation with me. I again attempted to explain the error of her ways but that's when she exclaimed that she was going to ride a different way. Annoyed that she was so thick headed and self assured that it wasn't her fault at all, I told her to try and not kill anyone else on her other route home but don't worry if you get yourself killed, it won't be a big loss.
