If he asked have you dated anyone outside your race I wouldn't be hating.
To each their own, asking that does not have to come from a place of hate, it can very much also come from a place of love.
Any lover of culture, even those not your own, can understand this.
Like imagine if there's a cuisine that you love to eat when it's authentic cuisine, of course you would not want that culture to be diluted.
And everytime there's an interracial offspring the kid never follows both cultures, only one or neither but i've never seen the kid following both.
