I love being a parent my kids is my life.
Some people think it's just physically parenting your child but it involves emotional, social, and intellectual child rearing you know?
I totally agree your kids is a reflection of you and just like you said you have to make sure you are always involved in all aspects. 
Yes people think from a biological perspective, but there are intricacies besides that.
The intricacies  is important because your kids go through alot and most parents don't know or realize it sometimes. 
Yes especially with gender, some children have difficulty with their masculinity or femininity and it can be confusing.
That is a big major issue in the US right now the gender situation and it is hard for adults to understand so imagine the kids point of view. 
Yes and one of the most important statuses of a person is gender, it breaks my heart that people can be so close minded, especially parents.
It makes me sad as well my oldest is 5 going to elementary this year and when I was growing up the topic wasn't one that needed discussing but this generation it needs to be address to kids early on sorry. 
If a child can't have their biological parents take care of them, sometimes even siblings can be open minded or grandparents as well.
