I would say it's still too much of a pseudoscience to be taken seriously.
What about it do you not take serious? Dominant traits are pseudoscience?
Lulz. Dominant traits including Huntington's disease?
Eugenics is a pseudo science because better is not a scientifically provable idea. Is it better for someone to be able to life twice their body weight, at the expense of years of life and quality of life at the end, or is it better for someone to be intelligent and live forever.
Eugenics is a wet dream perpetuated by people that have no perspective of true biology, or an incomplete misunderstanding at best. A trait that leads to a normal bacterium nearly dying, is also a mutation that will lead to a drug resistant bacteria being able to multiply at the same rate it would without the drug resistant gene.
Better is not a factual concept.
