I don't think anyone at all gets a tattoo these days and thinks they're being alternative. It's just decorating your skin, like putting on jewellery or make up

Also, IINM, user147... has been all over the boards in the last couple of days making mean comments for the sake of it - I'd ignore. (user, please enlighten the sheeple as to what sort of thing would qualify as less "yawn"?)
It's your body and you should be able to do whatever you want to it. However, you're asking about the pragmatics of prejudice against it.
I don't think we can answer that for you. But having RTFT, I'm pretty confident the key questions are:
- Does your current employer care?
- Do you think that that reflects on their approach in general - and would you want to work somewhere that did care?
I like that you take an alternative/atypical approach - from what you've said, the kids in your care aren't there because "the norm" works for them.
FWIW, I have a hand piercing, and my closest colleague has a sleeve (much of the "filler" still a WIP). We're in head office for a multinational. However I'm similarly anxious about first impressions, and if I were unsure - interviews, client-facing stuff - I'd cover my hand with a little spot plaster.
Sorry for War & Peace! TL;DR: employment is a two way street and in a good working relationship you make concessions for each other. You sound like you thrive in an environment that lets you be you, so get the damn tattoo
