uh yeah bud, cause it's wrong.
now you're going to say "it's not wrong I can longboard however I want"
yeah, you can. but people who ski way in the back seat also say that. then they plateau after they learn how to 360 and get shinbang.
if you know guitar, it's also comparable to people using the pads of their fingers instead of tips. it's just improper and you won't get any better at playing.
just cause it feels right doesn't mean it's right. it's not a matter of opinion.
