There is literally nothing circular, you're arguimg biological that does not exist nor would be supported as a causation for the phenomina we see in western culture. And you also do not understand anything about psychology or research methods given you are arguing things that any bachelor degree psychology student would account for in experimentation let alone fully educated publishing researchers.
You are arguimg feelings here and throwing away science because no scientist would ever touch the idea that race based discrimination at the biological level (which exiet to some degree) could ever be meaningful against the observed trends in modern day life and the piles of psychological data that imply this is largely social.
I'm not even trying to be mean but what you arguimg is exactly the enemy of progress in the field. You can't play off psychological studies to point to biology that would never argue explanatoons for the tremd we see in society. This has very little root in biology.
It's circular because we're going in circles. I can already see this. Our arguments have not changed nor evolved. We'll just have to agree to disagree. I'm an avid proponent to science, and I can tell you that the scientific community largely sides with my opinion about the problems with psychology. It's definitely one of the softer sciences, and not without good reason. I'm nearly infinitely more comfortable with conclusion based on biological evidence than I am with psychology evidence. Psychology doesn't hold up as well against the scientific method, due to its very nature, which isn't even debatable.
Our attractions aren't so digital. Every race has a diverse set of physical characteristics. To say you do not like 100% of a race because you don't like some of the characteristics is lotting all people of a race to have those characteristics. This isn't an innocent "oh I just don't like big lips/noses, sorry" thing. This is viewing a race as innately unattractive because they are a particular race.
If the argument is due to the conceptual ambiguity of race, them I concede my argument. If a single race can be virtually anyone, then sure, excluding an entire race for consideration regarding sexual attraction is racist. Of course, my original argument was in reference to the appearance of race (with specific features in mind), but I have no problem ceding that if what you're saying is actually what the argument in this thread is about.
