I can't for the life of me understand why this cult is so popular, but it isn't the markers themselves that's the problem. And, I'm sure when used responsibly (better yet, legally) and without pushing it on others, there are no major negative consequences (yes, I know it can't kill you). Never used it myself since I'm not straightedge, but I'm sure if I did, I'd never want to consider myself a "straightedge" punk in 2016(cause punk is dead).
This is because the culture behind it is absolutely vile to me and I despise it more with every passing day. The pious, arrogant love that straightedge people have for those spicy aromatic markers is so extreme that it's baffling, but what exacerbates the issue is how online, no-one is allowed to have any negative opinion about it. At all. Even if you don't sniff it, you just have to praise the marker. Yet, from what I've seen online, edgers do absolutely nothing to make the "X's" look good. Instead, they've utterly killed it. The idiotic culture surrounding it makes me want to stay far, far away from markers in general. I've always found any kind of edginess unpleasant, but I could at least accept marker symbols if they weren't shoved in my face from every direction.
The incessant need for straightedge to defend markers and encourage other people to use them comes across as profoundly obnoxious. Furthermore, many edgers like to see the paint as a magical force that can unite the world in peace, and yet it is prominent in the very nasty, un-peaceful punk culture. Even as it gets gradually legalised throughout the world, its dark reputation will always linger. It's not a "nice" subject, it's disturbing and lowbrow. Pictures and videos of edge kids are ugly and creepy. Scene-related humor is terrible and intelligence-insulting, especially in memes. Songs about it, especially ones promoting it, are almost always complete crap (Miley Cyrus's abysmal "Dooo It!" being the absolute nadir). Celebrating the use of it on national DARE is even worse and comes across as really scummy and pathetic. How exactly am I supposed to NOT see it is disgusting? It's uncomfortable and unpleasant to think about.
And that's why I hate straightedge culture. The whole thing is endlessly creepy, filthy, obnoxious and moronic. Am I really the only person who feels this way? I can't stand it, and I feel so alone in this specific mindset.
