Every time I see a post from Mastodon it's always some hate and rage driven rant. Like "I can finally say what I want so f* this and that". Anecdotal of course but it doesn't really come off as less toxic.
What you can do, is curate who you follow / block so that you mostly don't see that. TBF you could do the same thing on X/Twitter to an extent but the platform has an incentive to circumvent your preferences.
