Is AUTHOR wrong in the post ? POST : My brother (18Y) keep wanting a bike from my parents, 
Everytime he speaks about it the talk is going pretty bad my brother keeps swearing at my parents and annoying while I (16Y) won't interrupt or join in.

A little bit of background my brother works 3-2 times a week in a fast food place to get money for the bike but he needs help from the parents financially, they on the other hand do not agree to pay a cent for his motorcycle because it's on there responsibility that he will crash and get several injuries. 

He claims that he will get the motorcycle with or without the money and it's just badly effecting his studies.

Am I the asshole for not picking a side because I don't want him to get that motorcycle because it can be dangerous. But neither say something about it.

Big reason why I am so bothered is that my parents are always so mad because he makes them that mad so Everytime I talk or speak to them about anything I get shouts and screams.

Thanks for the help sorry if this story is boring i think it is.
