I didn’t see many 60 year Olds during recent rioting.
Maybe they passed genes along, but these guys are not the same as Woodstock attendees.
IMO the rioters are their ideological issue.
My recollection of the 1960s is that campus and street rioting were not anything like Woodstock. Woodstock was sex, drugs, and rock 'n roll; some of the campus and street rioters may have been there.
Campus and street rioting were New Left, Black Power, and anti-American violence.
