In my experience it's pretty easy to find non-toxic reddit communities. Most smaller subreddits for specific things are actually pretty nice.

But you need to be aware that's the recommended way to use Reddit.

A lot of big subs and even some default ones are extremely toxic, propagandist and authoritarian.

Agreed, it usually takes less than a minute to figure that out. Albeit, I usually don't ban it unless I find them hopelessly close minded when it comes to debates. For other subreddits, I follow them once I have seen them enough times to like them.

most sports subs are great, shoutout to /r/mma, best mods on reddit.

r/chickens is where its at.

Strangely toxic comment.

When a community is a sample of the world, and the world is full toxic people, then...

You don't have to host every opinion present in the world.

What's the point in hosting a discussion then?

Say we had a Twitter or Reddit but without the folks who eat babies. Wouldn't those still be super useful for the majority who don't eat babies? Or would they be worthless because there is some limit on the content?
