Our freedoms are primarily freedoms from oppression by our government. Nowhere do our founding documents guarantee us freedom from the repercussions of our actions or choices. Human beings do decorate themselves purposefully. Sometimes to come closer to an ideal or norm. Sometimes to move farther from those ideals or norms.
As it is difficult for us to see ourselves, most of the time, we do this almost 100% for the reaction it will garner from others, or the reaction we think, hope, or believe it will garner from others.
We dress in an expensive suit and get a nice haircut because it will make our employers and Clients look more favorably on us and helps us advance our relative position in the world. Or because we believe it will assist us in realizing our procreative goals/urges.
Punk rockers, gangstas, bikers, etc, dress in socially unconventional ways to set themselves apart from "straight" society, give themselves a more intimidating/aggressive mien, and to self-identify with their sub-culture. (Individualistic conformists.
... Or to emulate those in that society they think they want to be like.
Religious adherents nearly universally adopt some external appearance modifications or decorations which set them apart as a devotee. Hair, jewelry, clothing, beards, makeup and tattoos, hats, accouterments, ... heck, even ritualized genital mutilation.
There is a significant dichotomy here in the US in which we claim as a goal being blind to all of that, while ignoring the fact that these things were devised and enacted purposefully to divide people into recognizable separate categories.
We are supposed to have freedom from
THE GOVERNMENT treating us differently based on those factors. Certain classes of distinction even now enjoy protection from differential treatment by most private enterprise as well.
But there is no basic guarantee that your fellow American will ignore, not notice, and/or not react (based on his own notions and biases) negatively toward the choices you've made so carefully in how you present yourself to his eyes.
Now, HOW we may choose to react to those cues has much to do with our own ignorance or understanding, fears and security.
Someone who reacts negatively to a bearded man in a turban because he's afraid of violent islamists (when the man is obviously a Sikh) is acting out of ignorance, probably on several levels.
Someone who refuses to cross the street to avoid, or prepare his defense plan to confront, two young black men in gang colors and covered faces who just stepped out of an alley in front of him is also acting ignorantly.
It is a many-faceted issue.
