Wow you have no idea about human biology. A child who does not learn to detect human faces is considered disabled. You can tell a stop sign is a stop sign. But you can detect your mother or spouse from a million similar faces. And babies can do it before they walk.
Our faces are not just part of our bodies like an arm or leg. Our faces without our speech, are a communication devise. Like a dog can smell an other dog and identify them from just the urine. We can look at a person and know how they feel.
I am not judging her. I just know she is in an odd profession for someone who wants to have a tattoo that marks her so individually. That tattoo will be forever the first thing people want to know when they meet her. And if she stayed in her tribe that would not be a thing. But she is not staying in her tribe. So she will explain it like Paul McCartney will have to answer questions about the Beatles for the rest of his life.
I am not judging her. I am just wondering if she is up to the path she has set out for herself. I am not sure I would have taken the same path. I am the type who tries not to let anything about my attire give away my thoughts before I know someone. She has chosen to say, ask about my tattoo its a good story.
Biology has nothing to do with cultural symbols, or the heritage they are connected to. And in today's world, liberals don't believe in biology, or that it should even exist, or be taught.
