Not all that important to me if its sports or something along the lines. It boils down to value systems, belief's, morals, standards and view points. A perfect example for myself if I was to date is this:
Value systems: I believe in the structural order of the family. The man in charge and head over the wife, the wife is head over the child, the child in obedience and honors the parents. Family is very important to me and it needs to be for him as well. Any kind of strife is not something I want to be around, especially since I grew up with it all my life and is still going through that with certain members already. I am a sick person who doesn't need all that stress. I rather stay to myself than continuously getting hurt.
Belief's: I'm not a religious person nor do I believe in religion. I believe in God, read the bible, pray and go to church, as well as follow his teachings. But my relationship with God is first. I can get along with anybody who doesn't believe in God or another religion. As long as they are not trying to shove it down my throat I won't do it to them. If this person is interested in me, then he needs to understand my terms or he can leave. And no, some Christian men are no different. Many are counterfeits and use the Bible in a religious manner to bind a person and judge them unrighteously. I do not need a person who uses the Bible to justify themselves and to purposely hurt another person. Just because they don't believe in what you believe, they are still a human being.
Morals/Views: Pretty much everything in the Bible. But overall I need a person who is respectful and honors their family and friends. Somebody who is similar to me. Now as far as politics, I can care less about it. I don't vote and never will.
Standards: I hate smoking. I can never stand it or be around it. As a person with asthma, arthritis in the chest and chronic asthmatic symptoms, it is an immediate deal breaker. I don't drink, therefore drinking needs to be at a minimum, and not with somebody who likes to get drunk. If they do it is a deal breaker for me. I already live with a parent who drinks and that is bad enough. I don't believe in premarital sex, but I will not date a person for years who will not marry me either. Either marriage within 2 years of dating or I'll move on. If I date, its to seek a long term marriage partner that doesn't believe in divorce.
Overall you learn to come to the middle ground, talk and learn to communicate.
