There is a lot of confusion because some people believe that Free Will is denied if you accept everything you are is 100% genetic. That is false. Free Will is a concept for philosophy to struggle with. I am here to show you that the choices you make are all derived from a set of desires all of which are genetic. How well you go through with your choices and how well you peform in various actions trying to get to your goals; all genetic. Your beliefs even are genetic. The brains of humans follow geographical patterns like everything else. The behavior typical of a German is going to be more common in Bavaria than in Peloponnese. Some Nations of people are more impulsive, others are more methodical. Every axis and type of trait is based on genes and is more or less common along with related types of behaviors in specific groups of people. When immigrants come, some can pretend to believe what the natives believe, but as the immigration rate rises, the true beliefs of even the old immigrants become more overt. They do not think like the natives. They do not feel like the natives. They do not dream like the natives. This is because the brain structure and function is genetic. And so many of their genes are different.
How similar are you to the average chimp? (over 98.8% of average human DNA is similar to the average chimp)
How about a mouse? (~92% of average human DNA is similar to a mouse)
You have the senses you have of the world because of your genes; Eyes, ears, etc.
Your genes determine how receptive you are to ideas from other people, or how well you mimick behavior, or whether you are introspective instead of impulsive.
An african brought into Germany will never be a German. If all of Rothschilds money was spent to educate one family of Africans to make them as Germany as possible, their kids would still not be German. So long as they married other Africans, they would not become German, ever.
Whether or not particular thoughts seem more acceptable to you is based on your brain structure and the learned ideas you've accumulated. You've accumulated learned ideas based on your experiences. You could not have visual experiences if you have never seen. You could not have abstract thoughts if you can not understand them. The human brain is complex. An organism without that human brain capacity could not have human thoughts and understandings. Could you imagine a bat or Suncus etruscus to have philosophical theories?
Regulation of Gene expression normally happens in all of an organisms tissues on a continuous basis. This means that the environment is always a factor in how genes are expressed. Why does regulation happen? Because the organism contains mechanisms that sense various parameters. How does an organism regulate the genetic expression? Turning genes on, partially on, or off (simplified). That cells respond to the environment and adjust genetic expression is not proof that something or anything is not 100% genetic. Those mechanisms of sensing, responding, adjusting, and readjusting are genetic as well. A cell can not have a receptor that was not coded in the genome. A tissue can not have a function it lacks the mechanisms to do.
A country that does not represent any particular nation or nation(s) will be in turmoil until it is destroyed or remade. The struggle between groups of people exists even in apparent times of peace.
