Politicians always say or do something that leads to their downfall.

whether its a crime against humanity or embracement of Eugenics.

if your wondering, "What is Eugenics?"
let me explain.

Eugenics is a breeding process, it doesn't matter whether its sheeps, cows or humans. It is a breeding process made to get the 'purest' race. It is selective breeding. In it people of different caste, religion, race or country can't breed as their infant will be a mixed race/religion/caste which is so called 'impure'.

I'll give a few examples to make it easier to understand. Well, Eugenics has a different version here in India. Commonly known as 'love jihad'. Love 'Jihad' is basically the most stupid excuse to hate on interfaith marriages, specifically a interfaith marriage between any religious Indian with a Muslim.

It has even ben criminalized in the state of Uttar Pradesh

so in simple words, Love Jihad is a form of Eugenics. Another example is the treatment of Jews during N×zi Germany.

now to answer the second question.
Eugenics has a lot to do with politics even before N×zi Germany. Most politicians would embrace it. During the early 1900s it was seen as a social norm and was normalized.

now it has been reduced by a great extent, but it is still present in different forms in some countries. As I said before, Love Jihad is also a form of Eugenics.

And I do not support it, my girlfriend is a Hindu while I'm a Sikh meaning that we are in a interfaith relationship. I belive if the two people love each other and make their own choices, there is so problem.
