People should desist from this because this act is harmful, and it has consequences like emotional pain for your partner, feelings of betrayal, and it also has a psychological impact on the child.
DNA tests are becoming popular in my country. This might be because of the high rate of infidelity among couples or because science has made the test cheaper. It is now common to see a middle-class family going for a DNA test if the male suspects any foul play. It is becoming very difficult to be faithful to one partner due to social media influence and societal pressure. Women have been the main victim of this issue and I don't blame them sometimes. Women in our society have been subjected to so much pressure that they have to option but to engage in extramarital affairs. At home, she is been pressured to help contribute financially due to economic problems. And when she goes out to do business or get a job she will be under pressure to sleep with recruiters before she gets a good job. Customers will want to have sex with her before they patronize her goods or services. In some cases, these women have no option but to compromise. I will not support a woman who engages in extramarital affairs but it is important to hear her own version of the story.
3: When a child is switched at birth.
Secretly swapping someone's child is evil and people found guilty of such crime deserve a harsh punishment. I am sure this act will be rampant in societies that give more priority to a particular sex. In my location families will gladly swap female children for male because society sees male children as superior. But some women also deceive their husbands that they are pregnant and they go as far as pumping their stomach. After nine months they will go and buy or adopt a child claiming that the child belongs to the man. When a DNA test is carried out, it will come out negative.
