Am I a Pig for having a strong preference for Women of my own Race?

Some people find me to be a bit prejudice for only desiring to date and get intimate with ladies of my own ethnic origin and it is not due to the fact that I have any disrespect towards other types of girls. I like them as people and treat them with the same level of respect and regard as I would with any other individual, I'm just not physically attracted to them and I personally do not view this as prejudice. Although some people suggest that I am narrowing my options, I also know what my desires are and I believe that it is important to be honest about them. If I didn't have some selection in my process, then why would my date/partner have to be female in the first place. Are my thoughts and behavior acceptable, or do I need to open up a little bit?
