In my experience, of the people that CAN have their eyes opened to the truth, some people are simply repeating what they've heard without actually giving it any though, others gave the anti-Rights rhetoric only modest thought before accepting it as their own without actually considering the facts and numbers (which are on our side). Then there are the ones that simply fear what they are ignorant of. If I may borrow some words (brownie points to whoever figures out who's words): Ignorance leads to fear. “Fear is the path to the Dark Side. Fear leads to anger. Anger leads to hate. Hate leads to suffering.”
For this last group of people, it is difficult to truly accept that they fear the object and its capabilities because they simply haven't handled a firearm (hence, ignorance), so they mask it with anger at what a small number of individuals have used them for, and use this as an excuse to justify their crusade against the only reasonable method of self-defense invented thus far*.
This is why the best way to reach on-the-fence antis just might be an hour of range time.
*Firearms are the only implement, and the use of firearms the only technique, that can be wielded in self-defense by an arthritic, octegenarian female as effectively as a youthful, strong 31 year old. Only recoil may invalidate this claim I am making, which is why I am still waiting for recoil-less phasers and/or plasma rifles to come into existence, as these would then be the most reasonable method of self defense to be invented.
