Even back in the 60's they used to criticize rock music . I can remember being on the platform as a teen, reading the WT one SUnday and the article said the silliest things about The Beatles, Stones etc...to me continuing shame I did read it , I should have refused.
By the time that the major pogrom against Heavy Rock came in, I was married and an elder. I just ignored it. One Sunday I was supposed to conduct a WT study about "debased music" so we decided that an overdue family visit to an Aunt had to be done. I got out of conducting or attending that week.
I never made a secret of the fact that I enjoyed Heavy Rock, but of course I did not go around campaigning against their view either
It came in handy when I wanted to step down from eldership. The BOE and the C/O were persuading me to stay on...until I told the C/O that I had a practice of listening to such music.....end of conversation and I was immediately struck off...
BTW We all "knew" that KISS stood for "kids in search of Satan......."
