They make bmx look dumb as fuck. Imagine a fuckwit like Drake going back in time when rap music was NWA, Tupac, Biggie, and all the OG rappers. Now imagine his soft ass doing his whole yolo & started from the bottom shit, they'd probably put a hit out on him because he made rap look really dumb. Same goes for bmx, these idiots will inevitably make bmx look stupid by doing so. Adults already see it as a child's play toy, now they'd see it as something even dumber, making it harder to gain respect & seriousness when people want to petition for a skate park.
And I fail to see how that's a bad thing. Living in a single house with all your riding buddies probably fuckin rules. They all pitch in & get to save money by doing so for other things they want. A better house is nice, but not necessary. You don't need large, material items to be happy. They deserve it, but that doesn't mean they have to be entitled to do so. Why spend a fortune on a single house to live alone in, when they can share a house with all their buddies & have a hell of a fun time.
