Are you referring to women as “diversifying your portfolio”, then I would be worried as a parent, even if you were my best friend’s kid. Not based upon colour, but that statement just gave me chills.
Who wants their child to be part of someone’s portfolio?
If you had plenty of experience by 15, it sounds to me like you have been dating plenty of girls who were very young minors. And alcohol was involved -behind parents back. It doesn’t sound like a good start with a dad who had been told by someone that you were dating his under age daughter.
Makes sense that he would be extra worried about his young daughter’s boyfriend.
Yes, racism exist. But be sure you are not sometimes accusing people of racism when there are other issues involved- like promiscuity, age, religious traditions and so on.
