I agree to an extent. I don't see a problem with full sleeves, unless of course you've got some type of XXX porn or something like that going on. They're just tattoos.
Facial tattoos are another fine line, depending on what the tattoo is. If you're gonna emblazon a swastika on your forehead or something stupid like that, well...
Jewelry, piercings, gauges, subdermal implants, etc. all can be taken to the extreme as well, but still people need to calm down when they see someone with radical body art.
