You should see a 'delete my vote' option below the poll. That should do it!
As for me, my preferences have shifted over the years, but as of now, I'd say I'm definitely open to dating anyone. And while I'm sure I harbor a ton of subconscious biases, I feel like the only way to overcome those is to confront them head-on and embrace those 'uncomfortable' topics, etc. So in my experience, dating outside of my Race/Ethnicity has always been valuable and even enlightening in some ways. The woman I'm dating now lies outside of my race, ethnicity, and even nationality, but dating her has revealed to me a plethora of things about myself that I was previously oblivious to. Granted, dating within my race/ethnicity has been valuable too.
Somewhat related, but some members of my family have some rather strong views about dating outside of the race. I can understand them, though...even if my personal views differ. The world has come a long way, but living in the southeast region of the U.S., it's still pretty easy to see that racism is nowhere near dead, and that white supremacy is alive and well. Statistically speaking, black women are among the least desired women on the planet, and with the effects of white supremacy still very much in play, I can understand how someone would scoff at or even feel it disrespectful for an oppressed person to date someone who is not inherently oppressed. It almost seems counterproductive. I understand that, I get it, but I also understand the longings of the heart.
Thankfully, despite some of my family's views, they're still quite open and accepting of other races/ethnicities. In spite of their ideal wishes, I know they're open to anyone with a good heart.
