I can completely agree with the idea of "Sluts and Fools" as well as the fact that all of this starts at youth.
I taught a summer math course last summer as a favor for an old friend. The students were about 9-10th graders so they were about 14-15 years old. Now, in the program the rules clearly states that they must dress in an appropriate manner.
They must have not read that rules.
The girls wore tight pants and shirts that looked more like napkins = Sluts
The boys wore do-rags and hats and pants hanging off their asses = Fools
All the girls talked about was how they were going to meet their "man" or "boo" after the program was over and what they were going to do with them AKA sex. Same went for the guys in addition to checking out the girls in the class.
Now mind you, I'm not old fashioned at all. I'm in the 18-23 range but this was way too much to handle. One day for about half the class time, around 35 minutes, I didn't teach. Instead I gave them a bit of a reality check, telling them they shouldn't be dressing like this their age or even having sex and that by acting like this they were disrespecting themselves.
Canterro makes a good point. Humans don't change. If they do, the process takes an extremely long time. The next day some of the students were still dressing like the day before but then again, there were some students who actually listened to me.
