What stops people from dating inter-racially?

the only reason i dont is because i dont want a black or brown baby when i do have kids, i would prefer it to look at least somewhat like me, other than that there are some very y girls i would love to date, that are other races. but i think i might really get attached to them and then i would run into the problem later on that i told you about. mix girls (black/white) are some of the hottest ones i have ever seen , latin woman are the same, oh well, we cant have everything in life now can we.
