The second paragraph is born of a very strong feeling (stemming from experiences and comments) I've gotten when I've visited certain bicycle shops and been a member of certain clubs. That having to do anything to cater to a woman (so that she can get what she needs to enjoy the sport of cycling in the shop, or so that she is made to feel welcome in the club) is just an annoying hassle they would rather not deal with.

I'm not sure if it is a "threatened" thing, although that might be part of it. Maybe they have no clue how to talk to women or relate to women, and so if a woman comes into a shop they really don't have the faintest idea what to do with her or what she wants.

Or when it comes to the club thing, when the guys are out there riding on their own, they can be themselves. But if a woman joins the group all of a sudden they feel like they probably should make a few changes to make her comfortable, and they don't want to. They'd rather be just guys like they were before she came along. So instead of trying to get more women in their club, so that the women have the choice of riding with other women or being "one of the guys, they'd rather just get rid of the women all together.
