I still think it is horrible to judge anyone based on appearance. It doesn't matter if you agree with what they are doing or would choose that for yourself. I don't think we have the right to judge others based on thier appearence. Sorry, but it is the same thing as judging based on the color of ones skin, or someone's weight, and it is wrong.
Right or wrong, it's human nature. We all do it, all the time. We judge people, situations, events in a split second. It's how our minds work. We can try to be open minded and give people the benefit of the doubt but the reality is that the old adage "you never get a second chance to make a first impression" is absolutely true.
Having said that, there is a huge difference between judging somebody for their appearance...tattoos, piercings, hair and clothing styles...and judging somebody based on the colour of their skin. You
choose how to wear your hair, which clothes to buy, whether or not to have visible tattoos and facial piercings, and you have to acknowledge that you
will be judged for those choices. Nobody, (with the notable exception of Michael Jackson

) can control the colour of their skin!
I will never give my kids permission to get tattoos or facial piercings. Hairstyles in this house will be in line with
my idea of "normal". My husband used to tease me and say he wanted to get a tattoo and I always responded with "Make sure you get one that your next wife will like".
