umm, I don’t think we have clarity. im not sure where you came up with the beginning of your post, about motzei shem rah. I said I was talking about expecting bad things from a group of frum jews who have not done anything yet. joseph said (and I believe I am paraphrasing without altering it) that some frum yidden will now come forward and say bad things that are knegged halacha (rationalizations about the superbowl).
THIS is jumping to a conclusion, regardless how sure you are, that yidden will sin. he judged them infavorably, accusing them (although we don’t know specifically which ones, but Yidden nonetheless) of being sinners without a limud zchus that this year they might be different. there is no room to say he was standing up for Halacha in the face of evil, no evil had been done except in his negative expectation of members of klal Yisroel.
