Question: If they are so acceptable why do you have to hide them?
Answer: Because they make you look like a low-life and your white collar employer doesn't want the public to think low-life's work for him.
Yet, I’ve seen teachers, accountants, computer scientists, engineers, financial advisers, lawyers, nurses and medical doctors, all with visible tattoos.
::mind blown::
Further, you simply said getting a tattoo is not a good career move. And I pointed out that as long as one can cover them, it won’t affect their career. Thus, it’s not necessarily a bad career move, as long as they can be covered.
So, both your arguments fall apart.
