Okay...I read half way through the thread and got sick of hearing the same 2 things rearranged.
Here's my two cents:
In response to the original question, I'm not only tattooed, but a white guy with dreadlocks, and I get all three responses on a daily basis.
You WILL be judged on the personal choices you make. I know I am. It's a load of @#$%, but hey. I can judge people right back. I'm usually right too. The suit who works as a county prosecutor may judge that I'm a lackadaisical hippie or white trash, and that's fine, because I would judge him as a hypocrite, and guess who's right? Me. Said prosecutor just got busted for DUI and hit & run.
I've made a few personal choices, appearance-wise, that a majority of AMERICANS would and do stereotype me for.
My first tattoo was a full forearm piece of my band's logo done by a methed-out ex-con who ended up putting the high E string he had sharpened into the machine backwards. After drilling me for an hour with the dull, jagged end of a guitar string, I made hm stop. Never got it fixed, because most reputable artists won't touch it. It looks awful and it's right out there for the world to see, but do I regret it? No. Like I said, anyone who judges me based solely on the way I look is a hypocrite. And like Joe Strummer said, "If I get aggression, I give it two times back."
Personally, I've come to thrive on the misconceptions my appearance causes. It's made me a much stronger person, Ten years ago, before I looked so, uh, intimidating, I would get pushed around and put down and never stood up for myself. I'm not talking about violence either. Violence is the last resort of the incompetent. I'm talking about self-respect. After ten years of people giving me looks and comments, I've come to respect myself much more as an individual, and you can bet your bottom dollar that I'm going to stand up for myself and my beliefs.
In summation, if you have to worry about whether or not you should get a tattoo because of perceived cultural stigmas, or because you may regret later in life,you definitely should NOT.
It sounds to me like you aren't tattoo material.
