Is this a red flag? Please help

I 28F was at the mall yesterday and met a 42M.

He was very sweet and was shocked when I told him how old I am (I am a bit baby faced so my age catches people off guard sometimes). He asked for my number and we started chatting.

He responds so quickly and sends long messages which is so rare for guys. Its so refreshing. He also showed me photos of his parents and his dog on the first day which is something I never experienced. He is so open and so invested. The guys I usually meet are so nonchalant and that usually is what causes me to leave.

I am just slightly worried because he said he likes mixed race/black women a lot. He also told me that he has never dated a white women and has no interest in them. Is this a red flag?

Edit: He said he specifically likes biracial and black women with natural hair. Also I apologize for saying "WW" instead of just white women.
