@Waiting on him Anyway I think it's plainly self-evident that people who really appreciate fine, carefully done tattoo artforms include conservative, traditionally minded people.
One of the OP quotes says:
I am a nurse in a cardiac ICU. I am also pretty heavily tattooed. I am a well educated, well rounded nurse, and was raised with strong morals and manners. .. I am an extremely traditional person. I've always worn long sleeves .. I love having a professional persona as well as a unique one while I'm not working
In my humble opinion it's pretty self-evident that this is the case today. It often gives a real sense of individualism to the person who does it, including to very conservative-minded people.
In their professional lives people can be somewhat regimented (and I guess that sometimes it's with reason that this is the case). To go from time to time for some ink, to have tucked away, can be a sort of private or semi-private release and a sort of opportunity to retain a quiet, art appreciating sense of individuality in the regimented, professional world of day to day. As the person in the quote seems very strongly to recognize.
