People cannot choose who they are attracted to. Attraction is not a choice. Attraction at it's core is based upon Darwinian principles. A man who exhibits confidence, maintains eye contact with a woman without looking away, has money to be a provider, physically fit, very intelligent, emotionally stable, his attitude towards life in general (has a positive outlook and nothing brings him down), how well he interacts with other people; the fittest women, will want this man. Beautiful women know they are beautiful and thus know they can be choosy. The same goes with confident men who seem to have all these traits, they can be more choosy as well. Humans choose mates based on the mate's survival potential. The traits that I listed above factor in on human's survival potential. It determines, not only what sort of mate you will have, but what sort of children, what sort of success in business, life and your social life. The weak minded, those with poor attitudes, little self confidence, don't take care of themselves, they generally do not get to choose from the best in the mating pool nor do they have as much success in life.
Like, take for example, a fat person who goes for a job interview. The person that is interviewing the fat person will think, without even realizing they are thinking this, "hmmm, this guy doesn't even take care of himself, why would I trust him to take care of my business?" Automatically, without any words being said or neither person knowing each other, the fat person is not getting respect because the mere fact he is fat demonstrates an appitude for low survival potential in the minds of people. Heck, scientific studies have proven that fat people generally don't get good service while shopping, have social problems, harder times finding jobs, make less money generally speaking. It is because humans are thinking, without even realizing they are thinking, that fat people exhibit low survival traits and it does not garner much respect. It's the law of the jungle out in the world, the law of DARWINISM.
