Eugenics is the self-direction of human evolution. It is the study of hereditary improvement of the human species by selective breeding. It is both a science and a social movement. The idea is to increase the number of children of those with favorable genes (such as intelligence, good health, positive personality traits, good looks, etc..) and limit the number of children of those who have unfavorable genes (such as poor health, lower IQ's, mental flaws such as anti-social personality disorder, and physical defects) thus improving humanity's lot.

People often do not understand there is a different between positive eugenics and negitive eugenics. An example of negitive eugenics is forcible sterilization of people with mental or physical defects. An example of positive eugenics is encouraging those with good genes to have more children.
There is nothing wrong or evil with wanting to improve humankind. Eugenics is widely practiced by those who breed animals in order to produce healthier, more even tempered, better looking animals, why not on humans?

The applied science of improving the gene pool by selecting positive DNA; this is called positive eugenics, and by removing the negative DNA; this is called negative eugenics.
Eugenics breeding genetically changed the wolf into a domesticated dog; imagine what we could do to humans.

Eugenics is a social philosophy] which advocates the hereditary improvement of the human race by selective breeding. The supposed improvement generally comes down to ridding mankind of stupidity], which few people will disagree with unless you're talking serious politics], in which case the general consensus] is that it'd be best if mankind goes extinct]. To avoid confusion keep the following in mind, the Nazis] favored eugenics, therefore eugenics is wrong.
You know you’re too deep into eugenics when half your friends are White Nationalists since they’re the only ones who actually listen to your ideas.

The simple idea that stupid people shouldn't breed.

Politically correct people will defend the rights of those with Autism and Down Syndrome to have children, completely ignoring the fact that-

a. People with low cognitive skills are unable to care for themselves, let alone another human being.

b. The pain caused to these people when their children are taken away (for their own good).

c. The high chances that the child itself will be disabled, and have just as hard a life as his/her parent(s).

d. The high cost of medical care for someone who can contribute little or nothing to society.

In other words, common sense.

The study of Eugene.
We were learning Eugenics while watching Hey Arnold!

Eugenics are the practice of isolating negative genes, and preserving positive ones, whether through natural or social selection. Several attempts have been made, throughout history, to do such, with human intervention - all were short-lived, but none succeeded. Such methods toward eugenics are: genocide, bioengineering or genetic manipulation, and selective breeding.

Through natural selection, random or adaptive mutations occur. If positive, in theory, the traits should prosper. If negative, or not beneficial, however, they should fade away, if the family possessing these genes doesn't die away before then.

With human intervention, this is accelerated - the isolation of carriers of certain DNA can be achieved without blood shed, simply if no other group interbreeds, or if such a group discontinues populating. However, more macabre means can be undertaken to reach this, such as genocide. Still, yet, there are further, and possibly more promising methods, such as genetic manipulation, for carriers of such a trait could be "cured," rather than phased out, or exterminated, altogether.

Examples in history, involving humans, include: murder, en mass, of American Indians; the Holocaust (1933 - 1945); the Balkans ethnic cleansing (Bosnia, Kosovo, primarilly); Rwanda; Sudan; etc.
Ahh, eugenics - something that hasn't happened for quite a while. However, I feel it should. This could, quite possibly, benefit the human race, for without dumbshits, we should prosper much longer. Unfortunately, though, it seems the degenerates breed more, and faster, than do the good ones among humanity. 'Tis a shame, truly. Have no misconceptions, however, as I don't wish for races to be exterminated, but rather, unfavorable genes removed.
