They would then be the vanguard of the third wave, no?  3rd wave probably started in the late 60s with the counterculture.  Those hippies didn't want anything to do with the workforce like the second wavers.

Nope, Second Wave, starting in 1960 with the arrival of the birth control pill (alternatively, in 1963 when Betty Friedan published 'The Feminine Mystique'), and ending in 1982 with the failure of the Equal Rights Amendment.

The Third Wave wouldn't start until the 1990's (riot grrrl, feminist punk subculture, Lilith's Fair, slut walk nonsense) and the Fourth Wave started in 2012 (intersectionality, cancel culture, social justice warriors).

The First Wave is known for the suffrage movement, but they were equally concerned with Christian morality, the abolition of slavery, temperance (drug and alcohol prohibition), and closing down brothels (they were remarkably religious and conservative).
