Meet Jessica Jin. Texas Tribune:

The Cocks Not Glocks movement was created by UT alumna Jessica Jin last October after she learned that sex toys, but not firearms, would still be banned in classrooms. 

“As long as you have a dick on your backpack, people will be thinking about the guns inside of other people backpacks” Jin said Tuesday, dildo strapped to her backpack.

On the Cocks Not Glocks Facebook event, Jin wrote: “The State of Texas has decided that it is not at all obnoxious to allow deadly concealed weapons in classrooms, however it does have strict rules about free sexual expression, to protect your innocence. You would receive a citation for taking a dildo to class before you would get in trouble for taking a gun to class.

At this week's protest, the students not only protested campus carry with dildos, they registered over 400 people to vote.

That's how you do it.
