i mean, you can take a razor blade and disfigure yourself for free , or buy 10 cents worth of gasoline and burn it off. if you have an angle grinder just go out to the shed, problem solved.
but seriously, i use to work in substance use services etc, i would meet a lot of people who got tattooed in prison for whatever reason, survival etc, and now are plagued by their old tattoos. it wasnt so much about a nazi ideology for them, just prison shit.
i use to help them get them removed.
you are right, you can cover it with some bullshit. a lot do, they just black it out.
anyways, im not really going to judge etc. im jsut saying its not always easy to cover up a 12x12 fully black swaztika across your entire back and a giant iron eagle swazi chest piece, white power down your arms, ss bolts on your neck etc etc etc. if it was a little thing thats easy, but a lot of these dudes are covered in the shit. its going to take time, money and skill.
