why is "party" rap looked down upon on the ic?

as i look thru the reason i see a a lot of disdain for party music, club music or whatever you wanna call it

ive seen plenty of posters talkin down on artists such as trinidad james, future, 2 chainz, lil wayne and others that i cant think of right now

and it mostly ny posters who dont even kno that they are bein hypocrites sayin its not hip hop, its garbage

i think that most of you forget that hip hop started off as party music, when it first starte in the bronx it was just party music, thats all that was made

now the same posters from the brithplace of hip hop shit on party music

please explain ny posters why you feel such a way about music that your community created and loved enough at one point to make it a worldwide genre
