Well, here's my concern, I worry my tattoos make people think I'm racist
Why would someone think your tattoo is racist?
I got them when I was young and didn't understand the meaning of the symbols. Now I understand that they may be offensive to people.
If your tattoo is a racist symbol it's understandable to worry about what people think. You could always have them altered or removed.
I think it's okay to leave them on. I've learned a lot and become a better person. You shouldn't judge people based on the work they did when they were younger.
If you have moved on from those times that is good, but if you aren't willing to get them altered or removed, you will continue to be judged.
