It comes from when I was going into the Navy.Well no, I used the word 'ignorant' due to your snarky 'scars' comment. You can make a point without being insulting to people just because you think differently.
I wasn't calling him ignorant just becase he doesn't like tattoos...
I was asked, "do you have any scars, tattoos?"
After that, I have equated the two. A tattoo is a coloured scar.
