im a millennial too ! im in my mid 30s and im currently dating a 20yr gen z black guy.
when i was younger, it was like that as well ! but, as much as i was attracted to black men, i fought through all of the hate and slurs from lots of people. even my best friend at the time in high school stopped talking to me because i began dating a black kid from another school. ironically, she has 4 black ******* now. but even though there was interracial dating before the millennial generation, those people mainly kept it hidden. i personally believe that is was us, the millennials, who really paved the way for gen z girls to feel liberated to explore interracial dating and/or interracial sex.
