I need to find out why people hated Disco so much for my history class.?

Disco in the 70s is what the Lil Wayne or the Jonas Brothers would be today. It was trendy and it was mainstream, and it lacked originality, everybody was the same because it was commercial. There was more people that liked it than hated it, because with every generation there is followers and teenie boppers that just go with the flow and buy whatever the record labels tell them to buy, but the ones who hated it were a huge group too. The whole trendy and commercial side of it is what caused the other people to hate it. With every generation you have those who get into the trends (Twilight, Nsync etc.) and those who fight against those trends and try to remain "true to themselves/real". The people who hated it so much are the ones who listened to Kiss, Led Zeppelin etc. Many of them saw Disco as the thing that was ruining "real" music. It was more of a cultural phenomenon though compared to Lil Wayne or the Jonas Brothers, thats not really a good example to compare it to but the only things I can think of. Maybe its kind of like how all the rap songs are auto tuned today. Auto Tune still isnt as big and cultural as Disco was, but I cant think of any other comparisons.

I loved Disco in the 70's

I wasn't around back then, but I can tell you from studying music that it was mass produced, generic garbage.

Compared to the pop music being grinded out today it was a renaissance of creativity, but it came on the heels of the 60's and 70's, one of the most creative times for musical innovation in modern history.
