A large gene pool is better than a small one, yes, but without some form of selection, deleterious mutations will eventually overrun the entire population.

CF has always been a site that welcomes people from different backgrounds and beliefs to participate in discussion and even debate. That is the nature of its ministry. In view of recent events emotions are running very high. We need to remind people of some basic principles in debating on this site. We need to be civil when we express differences in opinion. No personal attacks. Avoid you, your statements. Don't characterize an entire political party with comparisons to Fascism or Communism or other extreme movements that committed atrocities. CF is not the place for broad brush or blanket statements about groups and political parties. Put the broad brushes and blankets away when you come to CF, better yet, put them in the incinerator. Debate had no place for them. We need to remember that people that commit acts of violence represent themselves or a small extreme faction.

Ok. The problem is though that nature can still exert significant selection pressure if it wants, and if it turns out that the Aryans are going down, then having spent a few generations weeding out all the non-aryans will leave you up a certain creek.

Which is why I rather like the method of eugenics used in "Beyond this Horizon" by Heinlein. Simply checking out the eggs and sperm that form naturally and picking the "best".
That allows for people to exert influence, but also limits the speed with which it happens.
NOTE that this works especially well as a counter to your example as there is no preasure to prevent non-aryans from breeding or to have aryans breed. Just for each set of parent to try to select a better luck of the draw offspring.
(Note, in the same book a bit of "history" is discussed, a very different form of eugenics, the contrast is stark).

"Best" intentionally in quote marks? Surely there is no best in genetics beyond what is optimal for the environment. The problem with eugenics as I see it is we aren't capable of predicting the future to the degree we would need to to effect large-scale changes.

Eugenics is never a good thing in my opinion. However, that is a separate issue from whether forced sterilization is ever advisable as a response to reprehensible conduct. For example, where a parent has lost rights to multiple children due to abuse and/or neglect, I think that sterilization should at least be on the table as an option to keep him or her from causing more children to ultimately enter the foster care system.

I'm hoping you mean optimal in the environment. As in optimal for the organism in the environment.
I put best in quotes mainly because the process of checking available eggs and sperm would not ever generate the best possible. Even with perfect mapping and understanding of the genotype.
There are plenty of traits that are obviously good. Better eyesight for example.
BUT even with such not all variations are clear, which is better supperior near sight or superior far sight? An intelligent Eagle woudl disagree with humans as to where the balance falls.
So my best was best pairing of the eggs and sperm involved. Not looking for perfection even after 20 generations, just a speedup of natural processes.
EDIT: I decided to look up Eugenics. What I am talking about falls outside the definition as many put it. It does however fall within the broad denotive definition and in fact runs quite contrary to the popular connotation.
