So are we going to kick out in-group children from the country when their IQ scores aren't high enough? No? Then that is a a bad argument.
Also, I have been trying to avoid the whole debate on what IQ test actually measure...
The article is perhaps extreme and overly performative, but I think the central idea of "races" not surviving the near-future is a good one.
If race realism is correct then job quotas, immigration and education policy will cause a fair few problems, and if it's wrong then the very large amounts of suffering enduring by some ethnic minorities will be fixable.
So while this is far from the most important issue (that goes to things like ageing, possible dysgenic trends and the possibility of true AI), it's still pretty important by the standards of modern policy debates.

Frequently found are lies, deliberate misrepresentation, mocking, bullying.
That said, it would be rude to ignore the effort you've made, so:
The main actionable things the HBDers I've spoken to want include no longer automatically treating mismatches between demographics in employment, prison, etc as a problem and introducing testing for those coming emmigrating into their country.
Also, there is a weakness in testing, namely that even racialists think things like intelligence are partly non-shared environment, so if you set a lower bar filter from a population with lower average IQ, then while the people you get will meet your threshhold, their children would often not (assuming this supposed genetic difference exists), which is relevant to immigration rules.
