Moustache.
A while ago, I grew a goatee, thus gaining 5 cool points, kept it for a couple months, then gained 5 more cool points by shaving it off. When I finally did, I shaved it off in stages like sort of real-life Wooly WIlly. These stages occurred all within the space of an evening.
First I went with the moustache and soul patch. I could also try the "just the soul patch" look by cover the 'stache with my fingers. Then came the jazz dot, and just the bushy 'stache (never again). Next... phew... this is pretty shameful to admit... the Hitler moustache.
I know... I know... I've don't like Hitler any more than the next guy, mostly because of that whole genocide thing, but also because he's a bigtime ruiner. He ruined what is now known as the "Hitler" moustache. Not that it's like, particularly cool-looking or anything, but now no one can wear a "landing strip" style moustache without reminding every one of a certain facist dictator.
Moustaches in general have a bad rap, not as bad as mullets, but certianly moreso than other types of facial hair. Facial hair in general says a lot to us about a person's character, and you can proabbly visualize the kind of facial hair I'm talking about when I say "Cop Moustache", "Child Molester Moustache", or "Handlebar Moustache". You probably enviisoned the last one along with a top hat and coattails, if not a tied-up maiden and some train tracks.
But the "Square Button" Hitler moustache is the worst. Not only that, his whole freakin' Nazi party did a wonderful job of ruining the swastika. Before that whole mess, it was a perfectly innocous and pleasant symbol of quite a few religions denoting well-being, but now the Nazis have ataches a bunch of hateful semantic to it, and now it's a symbol of hatred and intolerance. Fuckers.
And the "Heil" salute? if it wasn't for the Nazis, we'd have a perfectly good way of showing our appreciation at concerts without taking the effort of lifting both hands in the air, and waving them as if we didn't care. Nor would we have to hurt our hands trying to give AC/DC that devil-horn hand-sign (Which is remarkably close to the ASL sign for "I love you.", but I don't know if AC/DC can understand ASL.). WE could even synchronize our one-hand salutes and say, "Heil AC/DC!", but nooooo.... the stupid-ass Nazis had to make it so that the only thing you can "heil" like that is you-know-who!
They even had some really good typography and graphic design, but now everyone feels weird studying them because they were made by Nazis!
Thanks a pantload, Nazis! At least we got a really good generic enemy out of the deal, and by good I mean really bad. I felt kinda bad when I had to shoot the dogs in Wolfenstein 3D, but had no trouble at all peelin' caps into the Nazis.
Now, I know many people fighting for Germany in World War 2 may not have really cared much for facism and were probably just trying to prevent getting arrested for disagreeing with the porno-pube-moustache-wearing madman, but if you meet a character in a video game or see one in an action movie who is wearing a Nazi uniform, you don't have to stop and think about motives or reasons or feelings, you just know instinctively that he is a devout follower of Hitler, an anti-semite, a homophobe, and just general a hoteful human being who you shouldn't concern yourself with after Indiana Jones throws him into a wheat thresher or something.
And what about Fascism? I don't even know what the philosophical tenets of Fascism are! I just know that they're bad because the Nazis liked them. It could be a valid form of government that the Nazis did all wrong, like Stalin did with communism. I guess I'll never know, because I'm certainly not going to be seen reading "A Fascist Primer for Curious Aryans" on the light rail.
Fortunately, the Volkswagen managed to recover from the Nazi stigma. Fortunately, the Volkswagen recovered from the whole crappy-car stigma, too.
For the most part, I guess we should just consider ourselves lucky that Hitler had bad taste in facial hair, as dictators seem to have. I mean, what if Hitler had worn a nicely-trimmed goatee? Or a baseball cap?
