Do/did you have a religious tattoo before reverting back to the default position of atheism?
I do. 3 of them. I severely regret it. Though I try to remind myself that it is just a part of the mosaic that is/was my life. I plan on covering/reworking one of them with an atheist atom tattoo. The other two require more inspiration to "fix", but they are small and shouldn't be very hard. Just waiting for a couple of great ideas.
Tattoos are permanent. If I want to express myself, I use my middle finger.
I have one tattoo that is from mathematics. Though I’m a fan of the subject, I would not say it’s my religion.
