I would be hurt and confused too. But have you noticed that cyclists, particularly men, can be pretty judgmental when it comes to different types of cyclists? I don't think Bike Snob is far off when he jokingly points out all the labels cyclists have for each other or the brands/types of bikes they ride. It sounds like his response is a combination of not wanting to see you give up the type of cycling he identifies with and also a fear of being left behind if you are doing something he isn't. My husband has this same fear of change and usually when I just go ahead and take the plunge, he'll be adamant at first and then eventually come around or convert to it as well.
