How do i tell BLACK GUYS that im not interested! and that i dont WANT THEM?

well im black myself (dads mixed black/white). but im not interested in black guys i like white guys and im always getting black guys on me and stuff trying to flirt but i dont see the attraction at all. and theres this guy chris he has a crush on me and everyone is telling me he's planning to ask me out, and he's a nice guy..but i dont want him and what should i say cause he suppost to meet me and a friend at a movies and theyll be a white guy there (parker) that im kinda crushing on now, what do i say to chris " oh im not attracted to black guys, sorry,now please stop" i mean i would say that i dont really care but i dont think itll be cool for me to say it, and not just him i got like 6 guys crushing on me right now that everyone's telling me about, do i just say i dont want black guys? and i dont understand why black guys at my school keep wanting me more especially after i go with a white guy
