The best "educational" method I've found to make anti-gunners see the light is to invite them to the range. I shot scholastic steel challenge and uspsa on the college shooting club at one of the most liberal colleges in the US. To say that there were numerous "educational opportunities" is an understatement.
In classes and on campus, myself and many other members, when we encountered people with anti-gun views would always invite them to our new shooters clinics. I would provide the guns ammo and equipment if they would go into it with an open mind.
Many would refuse outright, but of the ones that didn't, a whole bunch of them ended up not only changing their views, but joining the club... We went from a small club with 10-15 members my freshman year to close to 100 when I left and has only continued to grow.
