My Dad wants me to date women from USA.

Since I am not getting any younger, my Dad’s always been nagging me about dating US women. He even asked me to sign up to Latin America singles club just to get one. I told him I am not interested with those women but he just fired me back with lengthy speeches. It’s driving me crazy. I am more likely interested with Thai ladies but my Dad strongly objected. My Mom’s a Thai and she cheated on him. He still loves her, though. Dad doesn’t want the same thing to happen to me. I also told him all Thais are not the same but he has been so close-minded since then. He’s quite stereotyping. How can I convince him to stop that?
