Speaking as someone with a number of tattoos:
I love my own. They have a personal meaning to me, were thought about long and hard, and I researched the artists who were going to make these permanent marks on my skin to make sure that they were both talented and safe. That also meant that they were not cheap, and one of them took over 3 years to complete.
That doesn’t mean that I like all tattoos as some are not to my taste, but just as I wouldn’t comment on someone’s personal sense of style, dress, or taste in music, I also wouldn’t comment on their choice of body adornment.
For me, it’s nothing to do with who they are, just the same as if they have no visible tattoos would not have a bearing on it either.
