Yes, when there are several quotes in a post, a long paragraph is a long chunk of text.
As for which parts are relevant, anyone wanting to see the whole text and decide otherwise is welcome to click the link or find the citation.
I don't understand why you simply can't put the quote up in context. You're there and it's right at your fingertips so I simply don't see how it can be an onerous task for you. You seem able to find more than snippets.
Your actions, in only supplying snippets, appears (and I emphasize appears) to be a deceptive tactic, whether or not you intend it to be taken as such.
