How can a feminist claim all women are feminists at the same time claim she's intelligent educated, articulate?

The claim that all women are feminists is a miserably inadequate and off base generalization that drips from the mouths of the ill-informed. Also note that a sweeping oversimplification of that kind would have been vilified as a "logically invalid stereotypical umption" had it been suggested by any male who is not a feminist apologist.
