There's debate as to whether or not the Pastorals were even written by St. Paul, but assuming they were if we take this one passage and isolate it we end up running into a lot of problems; namely that elsewhere the New Testament--and Paul himself--doesn't take issue with women teaching and having positions of importance within the Church. If this were the only statement that Paul ever made, that might be one thing; but when the overwhelming witness of the Pauline literary corpus shows us that it's okay for women to preach and speak in the context of church, and it's okay for women to teach (Paul names a number of women whom he refers to as fellow co-workers in the Gospel) and we have a clear example of a woman teaching a man in the case of St. Priscilla teaching Apollos in the Acts of the Apostles.
Assuming Pauline authorship of the epistle here, it clearly needs to be read within the wider context of Pauline thought, not taken and isolated as though it stands on its own, at face value, no questions asked.
Of course if Paul isn't the author it's entirely possible that the pseudonymous author does have views which may have been in conflict with the rest of Paul; but since it is still Scripture it still needs to be read in light of and within the wider body of Scripture and not taken and isolated on its own.
