I mean if you've ever covered nazi Germany in a history class you've seen the totenkop
That's a stretch. I don't recall ever seeing a totenkopf in a history textbook. Maybe if you majored in history with a focus in WWII, but that's not the majority of people.
If you've seen popular media featuring Nazis you've seen the totenkopf.
I don't think I've ever noticed one portrayed in any media depicting nazis either. Inglorious Bastards? Sound of Music? The Pianist? It's a Beautiful Life? Schindler's List? Boy in the Striped Pajamas? Show me a screenshot from any of those movies that has a totenkopf.
If you've played the wolfenstein remake [...]
How many people is that? Oh, not the majority. Great.
Yeah, if you're totally unaware that the totenkopf is well known and exclusively Nazi symbol
I wasn't aware of that until I read about it in the context of Platner.
and you tattoo it on yourself
I wouldn't have anyway because I think it looks stupid.
at a tattoo parlor willing to give Nazi tattoos
I don't think those kinds of parlors exactly advertise themselves as such.
and everyone in your life that sees it for the decade plus you are displaying it
You still haven't convinced me that the majority of people even know what it is.
then absolutely you and all those people that saw and also didn't know are stupid.
I guess I'm stupid then.
You cannot get a Nazi tattoo by accident unless you're really really really fucking dumb.
I don't have any tattoos, but I can still see how someone might have walked into a tattoo shop, picked something out of their catalog and gotten it without researching the history or symbolism behind it. It's not that crazy to believe.
