One thing the article omits is that he was actually a physician from a good family in Argentina.
I'm a little embarrassed to say that I was 28 years old before I even found out who he was. I'd seen the T-shirts etc, but had never worn any of them. I had no idea of the history behind the man whose image adorned them. When I did find out, I was sickened that anyone would wear an image of him. Imagine if someone walked around wearing a photo of Josef Mengele on the front of their body.
Those who wear his image are either ignorant of who and what he was and are just trying to look cool, or they knowingly embrace the evil that he represents. The first group needs to be educated. The second should be beat within an inch of their lives.
