Your first sentence was fine, although I disagree that the term is intentional victim shaming.
But you came into a forum where people know term A, and went on full blast with "anyone who is still using (well known) term A instead of term B (that many people didn't even know exists) should be immediately discredited."
That's needlessly aggressive and doesn't really help get your message across.
Is it because the word "pig" implies that the victim hasn't kept Kosher and that the scam is god's punishment for that? Is there a general consensus that people who are "butchered" deserve to be murdered? This stigma was obvious and immediate for you, but I'm not picking it up. I don't wish to perpetuate the stigma, but you haven't shared what it is.
