I missed most of this, but a few points:
1) A symbol's meaning is what is read, not what is written. The Confederate Battle Flag is a racist symbol, and if you mean "I'm a southerner and proud" you can't just use it to mean that, because anyone who sees it will read you as declaring your racism, because that's what it means now.
Similarly, a biohazard symbol as a tattoo means you're HIV positive; Jasun's negative friend made a mistake by getting that tattoo. The mistake is NOT on the part of the people reading it and assuming he's saying he's positive. What HE meant by it is actually irrelevant. It's incumbent upon him to explain to people when it matters (which should be only when he's about to have sex, on camera or off).
I hope no one would dispute that you can't wear a swastika and blame people for assuming you're a (neo-)Nazi. It really was an innocuous sun symbol before the Nazis got hold of it--but it ain't now, and tough.
2) It really is possible that Axl was that naive as a teen. Racists are by definition unscrupulous people with nothing a reasonable person would call ethics; why would they hesitate to mark up some dumbass teen just for practice drawing the symbols for their AB brethren?
3) That said, it seems more likely that he got the tats because he thought they were cool, as a way of acting out. Since he was too young when he got them, he (or at any rate the tattooist) was breaking the law even if the tats had been hearts and flowers. Teenagers, as I may have mentioned, are often stupid and almost always clueless about a lot of things.
He may have had a racist past, even a homophobic one. Am I the only one who got called faggot in high school by guys who later turned up at the gay bar, with anything but a homophobic attitude?
4) The choice of stage name for him is kind of suspicious in itself. The most famous Axl is, of course, the notoriously racist and homophobic frontman of Guns 'N' Roses, Axl Rose. (Axl isn't his real name either.) Anyone believe that's a coincidence? Anyone think it's this kid's real name? Thought not.
5) According to what I've read here, Dink has not made Axl aware of what's being said here. I hope he does find out, though, because his reaction will be telling. He could, for example, have a tattoo artist block in the "14" and the "88" so that they appear as solid squares. That wouldn't take long or be expensive, but it would make it clear that he doesn't stand behind those sentiments.
6) The Celtic Cross? A racist symbol? First I've heard. And according to an earlier post in this thread, the idea that it's PRIMARILY a racist symbol is debunked by people who know about such things. To be watched, because the swastika effect could still turn it INTO a racist symbol, even though it predates CHRISTIANITY (let alone the racist horrors of the 20th Century) by a thousand years or more. And the Thor-hammer became a symbol of Norse Paganism only after Christianity came to Norse lands, and people who kept the old ways wanted something they could wear around their necks to declare their allegiance, as Christians had the cross.
Some Asatru (people who follow the Norse gods) are racist. Some are not. Just as some Christians are homophobic, and others are not.
7) Has anyone thought that maybe the thing that Dink found exciting about Axl was the fact that he had all these tough bad guy tats and yet was a sweet bottom boy? Or even "hah! Look at all this neo-Nazi body art...we'll show him sucking dick and getting fucked and REALLY piss off the AB!"
OK, that's a stretch. But most things are complicated, much as we'd like them to be simple. And I'd love to see video (because I don't go near such people if I can avoid them) of an AB mucky-muck watching Axl bottom and having his head explode!
