One major "ism" I forgot to include in my previous comment is egalitarianism. This false notion that men and women are exactly alike and completely equal has been extremely damaging and has caused great confusion and a breakdown of relations between the sexes. Again, God made them male and female, which means there are differences between the two.
Great comment, Anne, especially your recognition of feminism's role in this. God made them male and female and each sex has its own distinctive characteristics and roles within the family, the church, and larger society.
Feminism, along with all of the other worldly "ism" philosophies (i.e., existentialism, materialism, hedonism, atheism, and the grandfather of them all, humanism) do not have origins rooted in Scripture. When men are not men and women are not women, the whole of society suffers. There is an abundance of weak effeminate men and aggressive masculinized women in today's culture. It's easy to get frustrated with such men, but worth noting that they are the product of 50+ years of feminism, which insisted men had to be "sensitive and in touch with their feminine side." Ugh.
While I think there is more than one reason behind this deception and confusion in youth, I would chalk a lot of this up to the feminist movement. More than most, it has blurred beyond recognition the lines between male and female and Satan sure hasn't missed this opportunity! We get flack constantly for encouraging our boys to be boys and ours and girls to be girls - we are told we shouldn't make them conform to what we think a boy or girl should do. We don't know what God has in store for our children as they grow in Him, but as He made them male and female, He has already started them on their paths. Where are the parents now days and why aren't they helping to mitigate their children's confusion in a world that strives for this kind of chaos? I do pray parents would remove their kids from schools where Christ is not King and properly equip them before letting the lambs out among the wolves. The youth in this story are NOT happy, nor will they be after they've destroyed their gender.
