This is the logical conclusion of the breakdown of "traditional," gender roles and the patriarchy. You give the left an inch, they'll take their mile.
The left is a force of disintegration and chaos. Traditions of every kind are what they seek to destory and all our traditions are interrelated and interlocking.
This is a tough reality to accept. But "women's liberation," and gay marriage open the floodgates. And we won't close these floodgates until we restore things to way they were. Maybe not precisely as they were, but something close to it.
