Yes, but so are Facebook and Twitter.

You can apply the same arbitrary granularity to bodybuilding.com (different subforums) and 4chan (different boards) too, and say 'such and such subforum isn't as toxic as these other ones...'.
The point is that all four platforms spread and foster toxicity. And given that Twitter and Facebook are magnitudes bigger, they also do so much more than 4chan or bodybuiding.com.
One FB/Twitter, you can only see stuff posted by your friends, friends of friends, specific people whose names/usernames you know and have searched for, groups you have chosen to join, and ads they show you. The other 99.99% of content is invisible to you.
There is a difference though as those platforms have larger moderation resources though.
