I know people are raised racist and get educated and end up more accepting, but do people ever grow up open-minded and end up racist or misogynistic?

Just for clarification I’m a little intoxicated so this question is a little edgy, but a real question none the less.
I’m just an athletic to average Caucasian man in physical form, but I’ve always been open-minded my best friend in school was of a different race (as if there are other races than the human race) just saying, but a different ethnicity and my ex wife was a different ethnicity and my child is mixed, but as some of you may know my ex cheated with a black man and as a white guy for the first time in my life I feel kinda insecure and a little pissed about it.
I have a good body, but not like an abnormally big whatever?
Do I have a right to feel like I gotta up my game and make the most of my good qualities because there’s kind of an underground sexual race war going on right now?
Like I lost my terrible ex wife to a black guy, should I be mad about that because women are not into me anymore or should I just be content that she’s not my problem anymore and maybe some women out there are happy with a regular body and just wanna be loved?
Am I going crazy?
