if you had a daughter would you protect her from guys? and if you had a daughter would guys change their ways on how they treat women?

I do have 2 daughters and I would do anything to protect them from anything or anyone who threatens to harm them. When it comes men, I know all I can do is share advice in hopes that they listen and learn.

I'd try to keep her informed and teach her to protect herself. My younger sisters have taught me that you can't do all that much to protect people after all. They're going to do what they want to do, especially if you tell them it's not safe to...whatever. Trust just anyone?
I think the only way a guy would change over someone having a daughter is if it's also their daughter.

I wouldn't want to have a daughter in this day and age

Yes, absolutely.That would be my chief concern of protecting her from unwanted people.Not sure about the next part.
