I think they're asking "If you use one only for specific circumstances, what are those circumstances?"

Oh sorry, my reading comprehension is clearly lacking :P I've been eyeing LibreWolf for a while, but I'm mostly too lazy to switch my addons over.

Mozilla is shitty, so you're opting for Google instead? That's like saying the air quality is bad, and opting to jump in the ocean and drown.

I use EndeavourOS. I like pacman and AUR, as well as the fact that Arch-based distros are well-supported by most software. I'm too much of a noob/too lazy to setup an OS without a GUI installer though, which is why I prefer Endeavour over Arch.

Finally switched from from Windows to Linux (specifically EndeavourOS, an Arch-based distro with a GUI installer).

I also bought a new phone, on which I intend to install GrapheneOS and distance myself from Google's ecosystem.

I signed up for Proton Mail.

LibRedirect browser addon to switch to privacy-respecting frontends for popular websites.

We’re talking about aggressively anti-social people who don’t really believe in governance and humanism at all.

...so, your typical modern conservative?

I say that slightly tongue-in-cheek, but I do stand by that the people you describe are almost exclusively going to be right-wing.

That's definitely not to say that there's never been any online communities negatively impacted by left-wing politics. I can't even remember the number of subreddits I used to enjoy that have been overtaken by tankies/Stalinists/Maoists/Soviet-apologizers.

No doubt, I appreciate someone bringing this topic up because as you say, right-wingers will try to sabotage any healthy online community. They do seem to especially target local, provincial/state and national subreddits, which can be fertile grounds for propaganda. I'm pretty active on /r/newbrunswickcanada where there are definitely a ton of right-wing shit-stirrers trying to establish their perspective on issues.

But while moderation is important, the community has to be actively involved in making this space into what we want to see. A big reason /r/Canada sucks isn't only the presence of the /r/metacanada types, it's the absence of reasonable people. I also remember when /r/Canada was decent, and I didn't leave when I first starting seeing fashy takes, because you'll see those everywhere on the internet. I left because eventually I realized most people I could enjoy discussing with were leaving/had already left.

The more one participates in an online community, the more one can attract like-minded people to that community.

I'd say the best way is probably to post and comment stuff you'd want to see. Participate actively.

It's harder to change a community's vibe after its been established, so now is the best time to get some social inertia and make this into a more pleasurable space than /r/Canada.
