I really don’t think you understand. Even at the time it was written it was understood to be exactly what he says now (anti monarch). I know, I was there. The pistols and many punk bands expressed the frustration among poorer youth in England who felt (somewhat legitimately) that they were doomed to wallow at the bottom of the social ladder with no way of getting out and upward. They looked at the monarchy as representative of a caste system in England where if you were born poor, you basically stayed poor.
The first thing you do when you want to tear someone down is make them less then human.
Which is exactly what he said.
