If Mr. Schwyzer is truly "the most despicable boot-licking opportunist wretch" then I doubt he's a good representation of all men sympathetic towards feminism.
While generally far more successful than most of those people, Schwyze fits the preppy sensitive betaboy male feminist type, the kind of person who is likely to stuff a carrot up his ass then crow about how comfortable he is in his own heterosexuality all day. I partially agree with you, he is far more representative of jewry than male feminists, but a male feminist is a bootlicker and opportunist almost by definition.
The other kind is the man at the bottom of the desirability scale, guys like David Futrelle:
But ultimately we're all individuals, nobody's fundamentally defined by gender roles, wouldn't you agree?
If gender roles exist of course they fundamentally define us. If you were female, you would be fundamentaly different. Unless you are one of the former category of male feminists, in which case probably not.
