In reality yes, people do many things, but I am thinking about how to stay within the confines of what Jesus taught, to "stay in His teaching". I find that Jesus' teaching was radically family oriented, and I believe that the reason was, that family was created to show who God is. In the verses of Genesis 1:26-28, try reading "husband and wife" instead of "male and female", and there you have it, family in the image of God.
Genesis 1:26-28
26 And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.
27 So God created man in his own image, in the image of God created he him; male and female created he them.
28 And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.
