I have several tattoos on my upper arms, and you're right. Some people can be judgmental twits when it comes to any kind of body modification.
Plenty of perfectly sane people get tattoos all the time, and removal is hella expensive.
Everyone's entitled to some silly decisions in their life. In the meantime, wear long sleeves.
