Some women don't change their last names when they marry, and those who do aren't required to do so by law. Thus, they're doing it of their own free will. Do you oppose women having a free choice in this matter?
This. True everywhere, even Asia.
My wife never changed her last name; a few of her wedding gifts were bank checks ( ) with her first name and my last name : the banks would not honor those, and we had to go back to the gifters...
Our daughters are now saying her first name with my last name would have sounded cool, she should have changed. Of course, every time she comes across a new last name, my younger one tries it out with hers - 'just to see how it sounds'...
On name lengths - my first name is nine characters, last name is 13, and middle is 9 again. Unless I initialize the middle, it never fits many forms. When we closed on our home, we realized that one letter in my name was misspelled all over the papers, so I had to correct it, and initialize, in around a gazillion places. That was one time I envied my colleague named Li Ni or something, or even my wife, last name length 5.
