Your ideas will lead to eugenics

(from common pro-natalist excuses).

As anti-natalists we strongly oppose eugenics and for a very simple and clear reason, eugenics is an enthusiastic support of reproduction (of a certain kind that it favors), while the basic idea behind anti-natalism is opposition to reproduction of any kind. Supporters of eugenics want people who are desirable in their view to reproduce and others not to reproduce. Anti-natalists don’t want anyone to reproduce. The only connection between anti-natalism and ideas of race and species improvement is a strong opposition to it.

Some of the most prominent arguments of the anti-natalist view work exactly the same against eugenics.
Even in cases of reproduction with the aim of supposedly improving a race, reproduction is still necessarily a selfish act that can never be done for the sake of the created people (because before someone is created s/he does not want, need or has an interest to be created).
Even in cases of reproduction with the aim of supposedly improving a race, reproduction is still necessarily an act done without the consent of the created people.
Even in cases of reproduction with the aim of supposedly improving a race, reproduction is still necessarily taking a risk on the one who was created without any request, expression of desire, need, or an interest of the created.
Even in cases of reproduction with the aim of supposedly improving a race, reproduction is still necessarily causing suffering to everyone whom the created would harm throughout life.
Also, in cases of reproduction with the aim of supposedly improving a race, and perhaps even especially in such cases, reproduction treats the created people as means to the ends of others.

Eugenics is not a moral objection to reproduction but a discriminatory and racist objection to the reproduction of members of a certain ethnic origin, or members of a certain social class. Therefore, if anything, it is a double sin in our view, it is both support for reproduction and for racism. On the other hand, there is no discrimination of any type in anti-natalism. Anti-natalism is an egalitarian and universal concept according to which no one should procreate regardless of religion, race and gender…
