> One of the most pernicious parts of Twitter is how people will retweet something dumb, offensive, or awful that an opponent said, along with a message mocking that opponent. Over time, this leads people on all sides of an issue to see only a distorted caricature of their opponents, comprised of an amalgam of all the worst features of that group. > How does Mastodon solve this issue? Well, Mastodon doesn't have retw…
It's not even the right problem.
The problem is not mocking people, disagreeing with them or whatever (incidentally the twitter character limit doesn't preclude external links or tweet chains, which are extremely common at least in science twitter). It's that doing so through a retweet (or a boost) is a signal to followers, and that can send hordes harassing a single person, because it's very easy for followers to click on the RT/boost and reply, and they're not going to see that thousands of people already did exactly that.
And the person at the other end of the pipe has to deal with a flood of burning garbage.
And more generally that kind of crap is easily weaponisable, twitter provides few tools to deal with it, and they don't usually apply their own rules. I don't know that Mastodon is any better.
Fundamentally, social platforms are only good so long as they've not reached their eternal September yet, or are actively prevented from doing so through active and unforgiving moderation — which can have its own issues.
