Just a thought, even if it might be controversial…
I think we should make it clear that there’s nothing wrong with wanting a submissive girl, any more than there is with wanting a take-charge sort of girl, or with wanting a roughly equal partner. I see no reason why any of those three styles of relationships won’t work, as long as they aren’t abusive. Some people like to lead, others like to follow. As long as the followers don’t feel coerced into following and are free to speak their own interests and desires when they choose to do so even though they may prefer not to do that usually, if submissiveness is just an attribute of their own nature, there’s no problem with it.
That being said, I think there’s a certain practical reason for looking to date within or without a particular race. If in your experience the type of girls you are looking for tend to be of a particular race, it’s only expedient to give a little more attention to people of that race in seeking a relationship. Race is of course not a determining factor in the absolute sense, but you can theoretically play the percentages and guess that a person of a certain race is more likely to have grown up in a certain environment or with certain cultural attitudes shaping their youth, and those things are somewhat legitimate predictors of a person’s nature. Not foolproof or absolute, but a predictor. You will of course find that not all women of that race, even if you guess right about cultural upbringing, have the qualities you’re looking for (unless it’s physical attraction, nothing wrong with finding some attributes more attractive than others, and that would justify dating one race exclusively, as someone said it’s just like dating only blonds.)
Race is no hard and fast rule for predicting a person’s attributes other than the physical ones. Still, if you’ve found that women of race A tend to have the qualities you’re looking for and women of race B tend not to, it only makes sense to at least focus more attention on race A. There’s only so much time in the day, after all, and there are alot of girls you could put your attention towards, and most of them are going to turn out to be unavailable or otherwise unwilling to pursue a relationship. It’s simply impossible to ascertain the true nature of every single person you meet. Racial features are an easy characteristic to identify for the most part, you can narrow the subset of women in any group you encounter to those of that race with relative ease and thus increase your chances of finding a woman who will be what you want. You may very well miss out on a more perfect woman by doing so, but you would be playing the percentages. You are trying to minimize the likelihood that you will spend a couple months dating someone and then realize they are incompatible with you. It will still happen, but considering the percentages it will happen less often.
In short, I think the motive behind choosing a particular race to date is what’s important. If the motive for excluding a race is the belief that people of that race are, in the entirety, inferior to others, that’s a bad motive. If the motice for dating only those within your own race is “racial purity” or “racial pride” or the desire to avoid “betraying” one’s race, that too is a bad motive. If it’s just a benign choice based on an accurate formulation of possibilities, I see nothing wrong with it. It’s recognizing a correlation in a certain percentage of cases, which is not the same as racist reasoning which identifies race as a cause and therefore universal. We have decided as a society that we can’t let corporations play the percentage game with race in their hiring, because everyone deserves a fair shot to prove their worth. With dating, nobody deserves a chance in the same fundamental way, the only person potentially hurt by your act of overlooking somebody on basis of their race is you yourself. You’re just gambling to achieve an objective. It may not be the method I would adopt, but I don’t begrudge anybody else his privilege to do that.
