I can't find anywhere in the parent comment or the parent's linked page where it was claimed that the ACLU's tweet of a modified false-quote-LARPing-as-the-actual-quote was "exactly" like 1984. The parent commenter appears to have used the adjective "esque", although perhaps it was run through the ACLU's false-quote converter first (in fairness to you, perhaps your comment was as well).
Might I suggest you edit your original quote ACLU-style and write something such as:
> Ah yes, [exactly like 1984].
Certainly, deliberate modification of words is fully acceptable as long as there are half-squares surrounding them.
The problem isn't advocacy, but quoting. They did use [brackets], so I hesitate to call the quote outright falsified, but since brackets are intended only for clarification, their use in this case is definitely deceptive.
They shouldn't tell lies about history. If a particular historical figure said something, say what they said, and don't put false words in their mouth.
Do you not understand that what ACLU did was showing deliberate contempt for the idea of truth itself?
> There's virtually nobody who quotes the US founders who is actually advocating for the precise same set of values and institutions those founders supported.
Yes, and that's fine, provided they quote them accurately and not deliberately misquote them.
