Women who are kind of ditzy often come across as more approachable - there is little fear in going up to them and asking them out. Even a "no" response will be met with a lot of gentle flattery and giggles, or maybe a hug and a "that's so sweet, honey, but I'm with someone." even if it is not the truth. So men know that there is little risk in asking out someone like that.
Women like that tend to bore me, though. And yes, strong minded, knowledgeable, and godly women with a good sense of humor are a great catch, but they are hard to get to know. Also, some women who consider themselves strong-minded are really just loud and caustic. This is considered "strong" by our society's standards - but our society is quite warped. I am making no assumptions about you, personally, but self-assessment never hurts anyone who reads this.
As I stated before - these quality women like yourself are hard to get to know, despite the many rewards. They are often engaged in whatever activity they are doing, be it work, or running errands, and are not really demonstrating that they are open to chit-chat with a stranger of the opposite sex. In fact, they are often put off by it. And at church, they are usually accompanied by a gaggle of other women, making it hard to talk one-on-one. So I'll turn your question around: How does a man meet and express interest in a woman like you?
If I were in Ohio or you were in Northern California, I'd have no qualms asking you out for coffee (or better yet, a glass of wine) just to see what happens. A "yes" would be great - a "no" would be okay too. Having survived a divorce that I wanted no part of, I consider that a much bigger rejection than declining the invitation to a date - so I know I can manage.
However, I am also big on friends first before dating. I'm not a big believer in the "friend zone" idea. I think there is a different type of risk than rejection here though: one makes the risk of making things awkward with one's circle of friends - one risks even losing her as a friend if interest isn't mutual. Ah, but what is life without risks?
