So, you are making a blanket statement about an entire group of people based on their race. It doesn't matter if the statement is "I am not attracted to them" or "They are all skinflints." The statement remains racist.

You are allowed to have preferences. If you have a preference about not dating an entire race of people, it is a racist preference, i.e., it is a preference based solely on race.

You do not have to hate a race of people in order to act in a racist manner. You are interpreting racism to mean something akin to "Walt Kowalski sitting on the front porch of his house calling his neighbors spics and gooks." Racism, like many things, is a spectrum. I am not saying you hate an entire class of people because your preference is racially biased. I am not saying you use racial slurs or would deny someone a job because of their race.

I have made, essentially, a proof in my prior post. Allow me to use variables this time to make it more clear.

  A= being racist
  B = making a judgment about a class of people based on their race
  C = deciding that you won't date ANY people of a race, because of their race 

  A = B
  B = C 
  Therefore, A = C. 

  QED, bitches. Until you can prove to me that deciding you won't date any people of a race because of their race is somehow NOT making a judgment call about a class of people based on their race, you have not proven that doing so is not racist. (Because I highly doubt you can disprove the first assertion.) 

Racism, like let's say all things, is a spectrum and it is not black-and-white. You don't have to spit on your black neighbors or assume they all smoke pot and Cools or call them "porch monkeys" in order to be racist.

If you say you are not attracted to a certain race you are saying "I am not attracted to that skin color." Because that's the only difference there is.

How is that not racist?

It makes it much easier to see exactly what I'm responding to, rather

I believe this is what that thing called "paragraphs" are for. But, Hubski as you wish; it's not my place to tell you what to do. You are entitled to do what you want and I am entitled to find it profoundly annoying.

Edit: You don't have to hate women to be sexist. So why would you have to hate other races to be racist?
