Common sense dictates that copying and pasting someone's work without acknowledging it is, in fact, plagiarism. It doesn't matter how you spin it or try to justify it with disclaimers. The definition of plagiarism is clear: taking someone else's words, ideas, or work and passing them off as your own without proper credit.
By the way, you showed an obvious example of NOT plagiarism. Kudos on that. So, let me ask you: are you genuinely interested in having a constructive discussion, or are you just looking for ways to stir up trouble?
