Appealing to "Gun Control Activists"

Keep it imminent and primal.
Just like said: these types are heavily influenced by MSM which knows exactly what it's doing by cultivating a climate of fear among the weak and easily-manipulated.
Trying to access the rational, logic part of their brain is useless when they're in a heightened emotional state — studies have proven this.
In classic 2 minutes hate fashion, whip up their negative emotional response to a perceived enemy, then coopt it for love of savior and hero — in this case: armed, lawful citizen.

If you want to reach women, show them the video of the newslady being gunned down by that nigger. That wasn't a mass casualty attack and could have been stopped by anyone with a gun and eyes.

TO BE ANTI-GUN IS TO BE PRO-RAPE.

Let them try to argue their way out of that one.

Rape is one of the left's power words. You need to work around it.

I'm not certain I could spin that one to suit our case, and the ones I could would get me banned from social media in short fashion.
Maybe that one with the Dutch news reporter and her cameraman getting stoned by sand youffs and the responding cops basically blowing her off: "When your last means of defense are gone, can you really expect the police to protect you?"

Paint a picture of how it's male privilege to go out inna woods and how guns level the playing field so that everyone can enjoy the sublime beauty of nature.

The problem is you need to work around the things that immediately throw up their blinders, of which Religion of Cuck™ is one.

Also a fairly good line of attack.

god fucking damn filter I fucking hate you

You can also sidestep guns and point stupid laws in England/Ausland i.e. no pepper spray.
Now THAT'S pro-rape and can really play into those fears.
And really dig into it, like bring up prosecution, sued by the rapist, etc. etc.

Yeah, that's a tall order.
The conditioning is strong in most normies.
Perhaps a more effective approach would be to locate videos of those same ethnic types saying in no uncertain terms what's going to happen once Whitey is disarmed.
On that, I think I'll look up that black instructor telling a group of youffs they wouldn't stand a chance against even a 12 year-old White girl in a firefight.
