I don't think tattoos are looked down on nearly as much as they used to be, but there are still some people who are very judgmental about it. I have a several friends who are pretty much covered in tattoos...a lot of them are police officers, soldiers, paramedics, firefighters, and so on. Sometimes people spend so much time judging a book by it's cover that they don't take time to get to know the story inside. It's a shame, really.
This is a very EXCELLENT post! While we humans are doomed to have first impressions (which in some cases is a good thing) we do have to remember to keep the mind open and not jump to conclusions that we "know" this individual completely just based on first looks. This is true for all appearances. I have witness people being rude to individuals who have the "nerd" look even well into the adult world. Judgmental people will always loose out in a lot in life.
