I'm sure you could find a noble, caring, beautiful Black lady to settle down with, buddy. They might be much easier to pursue in your romantic ventures, and as far as I know, they tend to go more for their own race.
I don't think being against miscegenation is racist, man. There's a reason it was frowned upon in so many cultures internationally for thousands of years, and it still is in many today. I could name a lot of reasons to be against it, both health-wise and socially, if you'd like me to.
There are still studied downsides to it that don't pertain to mixed-race children, and that you'd be better off avoiding in favor of dating some cute Black girl instead. To name a few:
Mixed-race couples have a higher risk of domestic violence, male partners have higher risks of alcohol problems, either partner has a higher risk of depressive symptoms (list continues in next reply because of character limit)
Lower relationship qualities have been reported from mixed-race couples far more than homogeneous ones, there's a higher risk for conflicts to generate in either partner's family against the opposite partner, and if you ever get married, there's a higher chance for divorce. It just seems, to me, like you'd be much happier in the future if you found someone of your people.
