Eh, I don't necessarily disagree with your statement -- and sure, I'd probably agree that evolutionary psychology has a problem in that it's not super testable -- then again, what does my word mean since I'm a lay person.
It does fit into our understanding of evolution though, and it fits into how we analyze behaviors of other animals. Its clear that some portion of our psychology is genetic, and therefore evolutionary, and it only follows that there's is going to be variability in each individual's initial psychological makeup, even within geographically adjacent groups of individuals. . When you plop nurture on top, that variability becomes even wider. Idk, it seems kinda nonsensical to claim that one person can't be more genetically predisposed to feeling anxiety than another, right?
You can and should call out racists, but just because there are some racists who use evolutionary psychology to be racists, doesn't mean it's all bunk. Just like it doesn't make Darwinism all bunk when it's used by social darwinists to oppress others.
Edit: obviously anyone who says "this race is more likely to act like this because of this" is whack. I guess I'm thinking of evolutionary psychology on more of a macro scale, where it could be used to explain (colloquial "explain," scientific "hypothesize"), for example, why humans experience social anxiety, where feelings of shame or embarrassment come from, how we deal with rejection, or acceptance, etc. in a real scientifically grounded way.
