Clarification: Of course, there are scrote athletes who got selected by the IOC to compete in the Olympics (accused of rape, abused drugs, cheated, sour loser, etc) and we should avoid men like that. What I mean is just like how the IOC only chooses the best athletes in terms of sport ability, we should do that too.
The International Olympic Committee has really strict rules when it comes to selecting athletes to compete in the Olympics. You really have to be the top athlete from a region to be even given the chance to compete. The IOC will not compromise its standards out of sympathy or whatsoever. This is why being able to compete in the Olympic is seen as prestigious by athletes.
Similarly, we should have high standards when it comes to deciding which men to date. If that guy has red flags, he should not be seen as a potential candidate in your dating pool similar to how the IOC will not consider athletes who do not meet its standards. The guys you date should at least have zero red flags (if you don't know the guy that well before dating) similar to how all the athletes competing in the Olympics are world-class. Dating is a selection process like the Olympic games. The first guy you date should not be automatically seen as marriage material similar to how the IOC will not label the first batch of athletes who qualify for an event as winners. The guy you choose to pursue a long-term relationship with or marry should be the crème de la crème from your perspective, similar to how the athletes with the best results win gold medals.
If no guy you've come across meet your standards, then just move on. It's not that different from the IOC choosing no athlete from a region to compete in a sport if no candidates from the region meet its standards. Being single is hence nothing to be ashamed about. Having high standards will just increase your chances of being desirable by men just like being able to compete in the Olympics is seen as prestigious as it's very hard to be given the chance to do that.
