I agree with Romeo Steven's comment that the issues seem orthogonal. As an example, (caveat YMMV), Steve Sailer believes in HBD. However, he frequently cites lower growth in african american wages as a reason to shut the american borders down to low skilled workers.

However, in today's environment, I'm not sure how many top-rated charities are HBD believing. A neoreactionary charity aiming at improving Africa might do many things differently. And being a relatively new ideology, most policies would not have substantial support of data. Hence, atleast in the current scenario, you would not find many people that were HBD aware and contributed greatly to african charities. However, it is not intellectually inconsistent.
