Not only was "We're Not Gonna Take It"
not some kind of defense of traditional, conservative American values, but Dee Snider was actually subpoena'd to appear alongside other artists before a Congressional hearing into "porn rock" convened in 1985 because "We're Not Gonna Take It" was one of the "Filthy Fifteen", a list of songs that the newly formed "Parents Music Resource Center" determined to be such egregious examples of the
attack on traditional, conservative American values by rock music that the group appealed to Congress to
create a national rating system for music similar to the MPAA for movies, in order to keep children from being influenced by subversive, sexual, violent, and occult themes in popular music.
The famous "Parental Advisory" sticker was invented literally because "We're Not Gonna Take It" freaked out American conservatives that much.
Fun fact! One of the other artists who appeared at the hearings was John Denver, a country/folk, artist whose music was for the most part considered so inoffensive and tradition-evoking that everyone just naturally expected him to side with PMRC against the evil rockers, and he surprised everyone when he came right out and called the PMRC Nazis.
