I remember talking to some severely lefto English people on a bicycle forum. Even they agreed that it makes no sense for one to be able to carry in a shopping mall, movie theater, or workplace, but not a college campus. There is nothing magical about college campuses.
I also think that the focus on young 'college kids' (which should be a contradiction) and the image of the 18 year old freshperson is a key strategy of the anti-CCW people. I'm a graduate student and I can walk around this building for probably a half-hour before finding anyone under 25. And most of them are more like 50. The focus on young college students makes it sound like the laws only ban young college students from carrying, and not the hundreds of older faculty, graduate students, staff people, and unaffiliated citizens that live, work, jog, and walk their dogs on college campuses every day, who are equally disarmed.
