Misogynistic Men on Monday: College guys

I wish I had a picture but alas, I do not.  There were a number of different signs and banners on move in weekend.  But I feel the cake is taken by "Freshman Fathers Thank You for Your Daughters." I have difficulty describing my feelings here. I will start with a list of my concerns and elaberate from there.

• RAPE! SEXUAL ASSAULT! HARASSMENT! okay so it's a lot harder than I thought to move away from this one.
• Fathers...so alone fathers are responsible for producing women for these men to rape(see I cant get away from it).  If I remember correctly from biology and well being a woman, there is this thing called pregnancy and it can be done without fathers.  Many women are single parents by CHOICE!
• The fact that this sign stayed up long enough for me to see it shows me that this campus's "commitment" to reducing sexual assault and harassment.
• There were women THERE! Other women were aiding to this! I can't handle that.
• Alright so I am going to play the HUMANIST card and say that this insults the one guy(who dates women) on campus that I know that would NEVER hurt a woman.  It is sad to say that I only know one for sure.(because the other three moved)
• And lastly, WOMEN ARE NOT PROPERTY! Men cannot give away or trade women like baseball cards. (Though many treat baseball cards better than women.)

Alrighty, so we have the blatent sexual assault invitation right there for the world to see and women go there.  I dont ever mean to be harsh on women but come on! I may not be good a picking men but I can see thats bad. And what ever happened to the fathers and their guns protecting their daughters? I know that sign was up for at least a half hour but I suspect it was there all day.  And no "freshman fathers" came to give these men a talking to?  Because if you look at it, it is insulting them as well. What father in modern society throws his (hope to be) virgin into the volcano? With the rise of purity pledges I suspect very few.  And on the other hand a least a few of those guys have to have had sisters.  Would they want someone doing that to their little sister? 
As I said this insults the few decent men on our campus.  Actually the guy I knew is very involved with the Mentors in Violence Prevention and Students for Sexual Consent.  I am sure that he would no be thrilled to see a sign like that representing his own gender.
On to the participating women, I know all through society people who are discriminated against for the same reason can join the dominant side in discrimination to gain power. It happened during slavery, in sex trafficking and internalized homophobia; but that doesn't mean I understand it.
My biggest issue, well next to rape, is the issue of women as property.  If these men only seen their female classmates as objects to be gifted to them, how much further until they are running a brothel for sex trafficking? It may seem like a jump but it really isn't that far.  

My question is how did they get this way? What did we do to make these men turn out to be what they are?
