Lol our bodies are designed to be with more than one person this has been proven. The penis is literally designed to remove another man's sperm from the vagina during sex. Also it has been a lot of research that suggest human behavior and norms are largely connected with your DNA coding but continue with your condescending tone
Proven where? Show where it has been 'proven' that your body is designed to be with more than one person. And also can you explain how a human being, who never designed or crated the body can determine what it has created for, it seems all they can d o is interpret certain things in a way to lead to a conclusion that they would like. For example...
You said that the penis is 'literally designed to remove another mans sperm from the vagina...' As if that proves the body is designed to be with multiple people. But what if that design of the penis is just a fail safe, in the event that it dies meet a vagina that has had multiple dikks it can remove then sperm and leave only its on like its meant to be. You see what I mean, even if the penis is designed that way it doesn't mean the body IS MEANT to be with multiple partners. That is an assumption which is the result of your preexisting bias.
As for your bit about human behaviour the sane thing apples, and I'll also add information or evidence suggesting something isn't proof of anything. And again it is all a slave to individual subjective interpretation.
The question I would then ask is, if for example human norms and behaviour is tied to DNA and coding then at what behaviors does it start or stop at? Is it feasible to believe only some norms and behaviours are coded and some are not? In turn how can we then judge human beings for any action or behaviour that may have been coded in their DNA and as a result they are hopelessly trapped to act out. How can we convict people of any crimes?
In relation to sex as our topic is, how can we shame pedophiles for attraction to kids when it may be coded for them in DNA. Like I have said before most people don't pay attention to where the rabbit hole they go down is leading. When it comes to science and research, studies and research take by scientists are funded by groups and individuals in the form if grants etc. These people who fund scientific research do so, so the scientific literature being produced suits whatever their agenda is, same way people and companies fund political candidates and parties. If you read a scientific paper or quite some research and don't not only read the entire thing carefully for what us actually proven but also spend even more time looking into the places and institutions where the study took place and the ones that funded it as well as the actual people who did the study then you are naive.
