The first line was in response to the large number of posts on here fetishizing black men, the rest of the post addressed those who simply say "I don't find black men attractive". Fetishizing is as destructive as simply saying "no people of color" because it again limits a human being down to some physical attribute or stereotype (usually big cock, or musculature or whatever) and is usually not about anything in a person's mind or personality.
As far as the other aspects, I'm of the standpoint that attraction and what we find attractive is a societal construct. How we are raised, the environment where we are raised, and the people who influence us have vastly more to do with what we find attractive than any biology, because biologically speaking, humans are human.
If attraction is learned behavior, it inherently is going to come with problems attached. The vast majority of American and European media upholds white standards of beauty--fair skin, straight hair, etc. The average fitness magazine has a white man on the cover. The average movie has a white hero, etc. Therefore, culturally, those things that are further towards the white scale are found to be preferable or more appealing to much of society. Why many can say "I find mixed race people attractive, but not dark skinned people".
A dating preference in itself is not oppression, if that dating preference is based on personality traits and choices. People don't date smokers, prefer to date people with similar interests and lifestyles, etc. Denying the possibility of dating someone simply because of race is a symptom of systemic oppression. The ability to boil a person down to the color of their skin and say "that's not for me" makes no sense psychologically. Attraction and lasting relationships are built on personality and human attributes. Just because someone finds a blonde attractive, doesn't mean they can't date and be happy with a brunette, or someone with different colored eyes, etc. It just seems incredibly shallow and vapid to base dating practice and preference on physical characteristics.
I have grown to be attracted to people I was not initially attracted to based off their personality.
And I'm not just concerned about homogenous environments in Eurocentric spaces. I firmly believe diversity is one of the greatest ways to happy, healthy, peaceful communities, and homogeneous neighborhoods, cities, or countries often lead to racism, xenophobia, classism, etc. I lived in Japan for a year and was bothered by the level of xenophobia (and the other side of the coin, fetishizing) that occurred while I was there.
