I support the right for college students to defend themselves. But you should post this on your state forum.
The age requirement for concealed carry is 21. Do you simply want concealed carry for those 21 and older? What self defense do students age from 18 to 20 get?
Florida does not generally permit open carry. If this were legal, students 18 - 20 could open carry, at least off campus.
My advice would be to help your state group work the OC issue and then work the college campus issue.
