But the clips and sources I have seen were of people saying that at that time.
i was born in ‘73 so I have no input.
I once saw an anecdote that when people say “I like all music except country” there is a hidden bias against “rednecks”. When people say “I like all music except rap” there is a hidden bias against “black culture” if not blacks themselves. I wonder if the “I hate disco “ started that way. Sure many if not most were referring to Disco Duck type things. But like many things once it goes mainstream then it does suck, like many genres.
