An adult man doesn't just join the Andrew Tate crowd. The foundations for agreeing with his misogyny were laid while he was a teenager (or even younger). The people who are alienated by this sort of rhetoric aren't adults, they're teenagers who haven't formed a political identity yet, who can yet be turned away from that self-destructive ideology and it is them who are turned away by such rhetoric.

The term "man" may by all of us be seen only to refer to males over the age of 18, but a teenage boy will already identify with it, will thinks of himself as cool, independent, grown-up. He will see an attack on "men" as an attack on himself.

While the targeted group may have been adult men, the actual targets will have been the twelve y/o Vaush spoke off and they will be driven further away from the principles of democracy and equality and into the hands of waiting fascists.
