Why is it so rare for people to find a partner outside their ethnic group?

Like since I developed attraction for females I’ve just been attracted to pretty girls of every demographic even though I’m a Jewish male myself. I went to diverse schools in the Bay Area growing up and nobody ever looked at me weird for liking a girl who wasn’t my skin tone or asking one out. I actually thought it was so normal that I found it weird to even prefer your own race because I thought all guys just thought of girls as girls regardless of race. Despite the fact that so many people coexist go to school and work with different people, why is it so rare for people to find love outside their own group? I don't know I just thought this was super normal.

I do not care about race but I prefer guys who resemble me in cultural values and lifestyle and food preferences and religion and musical taste and colour taste and that is a reason a Chinese guy might be more compatible for me or at least a religious guy that shares me values. I will give you an example, white guys might not like me cause I am sensitive to temperature changes so I won’t go skiing or swimming in Canadian lakes with them.

I prefer only Caucasian women for romantic interests. I don't mind other races as friends.
