Banning alcohol on college campuses is most definitely not the answer to curing rape culture on this forefront. Unfortunately alcohol is not some impossible to obtain substances that can be kept away from the reach of college students. Legal restraints and close police watch are just a few of the preexisting forces that are meant to put a cap on illegal activity taking place on college campuses and all other spaces in the same fashion. What these measures all but fail to do is the very thing they set out to achieve as students still find a way to smuggle their contraband into the space.
Rape culture cannot be solved by creating pointless mandates such as this one to restrict something the use of accoutrements that already have a presence in the wrong hands. Society has a tendency to want to blame illegal substances on the promotion of an individual committing a crime instead of putting all fault on a perpetrator. Cases like that of Brock Turner are living proof of the existence of not only legal defenders that are not working in the best interest of the community. Brock Turner received a major pass in the rape of a student at Stanford. Turner and his parents were committed to using alcohol as a coverup for Turner's lack of respect for his female counterpart, one that did not have any idea of what was going on.
Plainly put, it's time to stop assigning illegal drug use and alcohol as an excuse and in many cases almost a permit to disrespect women on the basis of their style of dress, speaking liberally, and acting out of the ladylike mold as defined by societal constructs. This type of behavior is working against the progression of the human race as it promotes the ideal that women lack worth and their bodes aren't as deserving of the same protection that the male species is deserving of regardless of a number of factors such as socioeconomic class, gender, age, etc.
