I definitely would! Why does race matter? Sometimes for some religions it does but I don't fall under that category.
My boyfriend is hispanic and I'm white and I'm perfectly fine with it. In fact, I kinda like having someone who is of a different race. It brings differences which keeps our ideas and opinions different. Like his family came from Puerto Rico and mine came from Scotland so our accents, type of food we eat, etc are different and I think that's enjoyable. They're not different enough to cause issues though, thankfully.
But anyway, to answer the question, definitely yes I would date someone of a different race. In fact, I am!
