Do you think feminism is a heresy?

Feminism is an error, not a heresy.  And it is an error that proceeds from liberalism.  Feminists are not cut off from the Church by virtue of their feminism, but by virtue of their liberalism and feminism, they are likely to believe or do something that does cut them off from the Church.

Isn't feminism a result of modernism, which indeed is categorized as an heresy?

Do you think feminism is a heresy?

If formulated as a theoretical apparatus that touches doctrines of faith and morals as infallibly taught by the magisterium of the Church, then it could be anything from a "malformed proposition" to a "theological error" to a formal heresy contrary to dogma.

A feminist may say: "God did not intend for man to be the head of a woman." This would contradict divine revelation as found in the Book of Genesis in the malediction of Eve.

A feminist may say: "The Holy Ghost is a feminine power." This contradicts the dogma that God is pure Spirit and therefore incorporeal. It's consequence can lead to grosser heresies regarding the Incarnation and the Virgin Maternity of the Mother of God.

However, a Catholic woman who endeavors to act like a man and wishes to impose her will upon her husband is not necessarily a heretic, though she would be sinning against the Sacrament of Sacred Matrimony and the order established by God in natural law.

A Catholic woman who invokes feminist principles in order to dress immodestly may not necessarily be guilty of formal heresy, though she would be suspect of modernism in professing such principles and her behavior will certainly bring about scandal and dissension.

Feminism began as an offshoot of modernism, and has become a practical way of life in the apostate Occident, only to find its way in theoretical and ideological formulae that certainly may be heretical.

It's part of trad culture in many places.
Even Bishop Williamson who says young women should not attend college but stay at home, applauded a wife taking on more of a "mothering" role towards her husband as filtering things and directing him.
