Do we value difference or fear it?

In the image above, I see an alien creature with many limbs waving hello, wanting to approach me, to form a peaceful relationship. What do I do?

In my own relationships, do I embrace those that are different from me or do I judge them and look for ways to say they are inferior in order to protect the images I have of myself? And what exactly are these images, these stories I tell myself of who I am?
