Yes, you attributed. But you very deliberately copied the article and posted it as your own work. You can't even say that you forgot to add quote marks as the text was slightly altered - evidently to give you an "out" if anyone accused you of direct copying.

Your threats afterward made things worse - much worse. Not understanding plagiarism (go look up the dictionary, or Wikipedia already!) whilst being an edito of a publication just makes this bad thing horrendous.

Make a full apology. Don't do it again.
