Are you really quoting Bronski Beat to me? Bronski Beat?
I know. As if Bronski Beat were advocating having sex with children like Nambla

They were just trying to get the age of consent in the UK, which was 21 at the time, in line with other nations.
And actually this was a mainstream gay issue in the UK, hardly a radical one:
http://en.wikipedia.org/wiki/The_Age_of_Consent
By 1984, many European countries had reduced the age of consent for homosexual acts to 16, but it remained at 21 in the United Kingdom, having only been decriminalised in 1967; the wording of the legislation to decriminalise also included wording that placed restrictions such as making illegal the use of a hotel room for sex.[4][5] Homosexuality was further stigmatised beyond the restrictions placed on homosexual individuals, and homophobia was a danger to gay individuals.
Against this background, Bronski, Steinbachek, and Somerville met in Brixton in 1983, and soon formed Bronski Beat.[4] They signed a recording contract with London Records in 1984 after doing only nine live gigs.
