I understand that this question involves a measure of subjectivity, but I am curious to hear people's opinions. I understand that getting a (real) tattoo is forbidden by Jewish law. I also know that the name of G-d/Hashem is very holy and not spoken. When I was younger, far less concerned about offending others, and not a follower of any religion, I tattooed קֹ֖דֶשׁ לַֽיהוה on my left hand as a wedding band. I am now in the process of getting this tattoo removed (my marriage is still going strong, in case you were wondering).
I am curious, however, if this would actually be deemed offensive to most Jews or not. Also, if there are any sources where this has been dealt with in the past I would love to hear them. Either way, I am still getting it removed.
I ask because I intend to soon attend Hebrew school as a Gentile observer, but I am debating whether or not I should conceal my tattoo.
