The data and the statistics on the subject of interracial dating and marriage basically says that you are overreacting to your own anecdotal experience because across the board in every racial and ethnic group all people want their own people at least 80% percent! Asian women are the number one group who date and marry out so you don't have to worry too much about white women!
So in the grand scheme of things you just have to get your game up as a man or hire a dating coach which believe it or not alot of men do! The pickup artist industry is going strong! If you don't have someone in your life that you can call in for help getting your swag and appeal up then hire someone. There are no cool points to lose for investing in your own development!
SO again I am telling you most white women want white men and the same goes with all other groups! You just have to get your game up!
