I agree with you that the worst of the worst in that instance will do exactly as you say. I have no interest in arguing with them, and if I see them here I'll block them.
But I am interested in acting as a counter to their hate, by having our posts show up in their feeds. If we can show their regular users how to have civil discourse, and expose them to new topics, we can get some to question the narrative.
They can come to our instance, sure. They can take part in our communities. But then they have to play by our rules, or get banned. Remember, a community lives on one instance and is propagated throughout the fediverse. Once they're outside of their walled garden, they won't be seeing that constant drip of hate.
And if any of that instance's users are questioning what they've read there, they can come to us for an opposing view.
