Maybe nowadays people are much more open to that sort of thing but I don't know.....
Yes, SOME people are. But the open-mindedness of SOME might not be enough to keep Spyderc0 from being unduly judged for having made a foolhardy decision to go and get his hand tattooed.
For example:
I personally wouldn't let a tattoo on a hand -- extremely bad idea though it is -- keep me from hiring someone I thought was otherwise qualified for a job beyond anyone else I interviewed. And I work in business settings where people dress to impress.
Having said that, my bosses -- 20 to 30 years my senior -- would definitely have a problem with a hand tattoo, and in hiring someone with one, not only would the person with the tattoo come under scrutiny, but I would too, for having hired them.
Generally speaking, I have enough going on for bosses to scrutinize without having to worry about their judgements regarding someone I just hired. Thus, my progressive views would quite likely get trumped by my bosses' traditional views.
My point is that even though social mores are constantly changing, it takes a long time for new views to become pervasive.
Spyderc0, while I do think your tattoo is a bad idea, I don't think that you are doomed because of it -- not like those who disfigure their ears with those huge posts, anyway. Unless, of course, you have those, too.
Regardless, I wish you a happy birthday and many more to come.
