Ludwig....the difficulty with this "fashion" is that its for keeps, unlike clothing, or some other frippery.
Our sexuality, race and physical ability is beyond our control....having these disfigurements done is entirely within his control, and therein lies the difference. He has made a conscious choice to look the way he has.
That is up to him.
The chap we were talking about yesterday is a rare sight....I personally have never seen one in the flesh, so to speak. He didn't have a butterfly on his ankle, nor a dolphin on his buttocks ( as far as we know ! ) Those are neither here nor there. What he has had done is a complete skin change.
The problem comes when he decides that he is bored with this new "fashion"
Unless you have an awful lot of money, and a very pain barrier, tattoos are, in effect, permanent. The reason that I and others are questioning his lifestyle choice is that he doesn't seem to have thought very far into the future.
If he really thought that this drastic disfigurement wasn't going to effect him in his future life, then that is his "lack of judgement " ....he has been naive to a huge degree.
