Australia

I dont really think this is a fair assessment.

Rowland Browne is a well established anti-gun nut, who other pro gun control individuals feel uncomfortable associating with.

This organisation that he's Co-Chairman of?
https://www.guncontrolaustralia.org/ ?
You could fit their active members in a Kia Carnival.

What they do have is a website and a fax machine, and they REGULARLY spam all the media outlets with "press releases", which those media outlets publish on a slow day.

According to Mr Browne, anyone who wants a gun for any reason is guilty of wrong-think.
"How dare thousands of wrong-thinkers band together to stop rightness!"

We're past the point of diminishing returns on gun control in Australia, but Mr Browne won't be happy until there isn't a single gun, nor the means to make them, and children aren't playing "cops and robbers" with bent sticks.

I'm a bit surprised we haven't heard from Phillip Alpers yet.

Edit to Add: The irrationality of the individual who downvoted me for calling out Mr Browne warms my heart.
You almost get it: you're one person, you get one vote.
But mate, so am I.
Pro-gun people aren't all paid shills, out here to promote the sale of guns and ammo like a shady drug dealer on a corner.
There are 940,000+ people who currently own them safely in this country and would like to continue doing so.

What happened in Bondi wasn't a gun control issue, it was terrorism committed with guns.
And the general public can see it.
