I want to argue about the words @Gargron used, but let's move on to content.
The challenge with quote-tweets not being available is that they are useful as a mechanism for contextualizing, and that alone can be used for good, or ill.
Can it be used for toxic behavior?
Yes, but I'd like to see more about why this idea of inevitability comes from, and I'd like this discussion without absolutism or rhetoric, hence my frustration.
