Not entirely, the idea was studying what the impacts are for these online dating sites in terms of how we tend to date anyway.
The actual study already suggests we tend to date
with our own prejudices, not matter how mild or extreme those may be. The study also suggests that the increasing use of these online dating sites has not necessarily made those sociological conclusions better or worse.
The study introduces the difference between passive ideological selection of a partner against the idea of sexual prejudices, and is also cautious in saying all of those who pick a partner within their race are not inherently being prejudicial.
Further the study itself in introduction and conclusion stresses the idea that "expanding people’s sexual horizons does not mean overriding some "true" or innate preferences; it means intervening in the unavoidable and ongoing processes by which our preferences emerge in our interactions with our social and cultural environment."
What it comes down to is looking at when prejudices are in the front of our decision making process and what we might be able to do about it.
The study goes so far as to say they are not interested in applying online discrimination protections (as applied to uber or lift) seen applied to online dating sites, including warning against the idea of what you suggest they want. At no time are they saying prevention of white people choosing each other.
What they do say is increase inclusion, not via exclusion of results that most of these online sites use to determine potential matches.
Sociology as a study suggests looking at the pitfalls of discrimination, that is seemingly all they did when thinking about online dating sites.
We might be overreacting here.
