Domino, you obviously don't understand the point of qualification. What you said to the girls is fine. It's also fine that they turned b1tchy on you and called you names. That just tells you they are feminist hors whom you should not ever get serious with.
How important is qualifying a girl? It's extremely important if you're looking for a serious relationship. Just paruse through some of the following blogs and you will understand where I'm coming from:

There's a reason for the 60% divorce rate (2/3 of which are initiated by women, while the man pays the alimony!). It's because men don't qualify women before they fall in love. They judge a women based solely on her beauty and ignore her lack of femininity and character.
If you're just looking for a quick lay, then no, true qualification is not important at all. In those cases, all you really care about is how hot the girl is (and possibly how many STDs she has). In such instances, you may want to tease the girl about qualifying her, but it's all really an act. If you're just looking for quick sex, you couldn't care less how well she cooks.
True qualification is designed for finding a quality woman to fall in love with.
