In that case you have been very fortunate. Animals, especially male animals that do not fear people can and do become very aggressive to the point of many, many cases of causing harm to people.Show me the science. Every animal I have ever raised with loads of socialization has known their boundaries with humans and been respectful. Every animal I bought raised by someone else took years to become comfortable around humans. You have your experience. I have my experience. I also have not been able to find any science that imprinting causes aggression. Until I see the scientific research to prove my way wrong or your way right, I choose to believe both ways have their benefits.
