The Chofetz Chaim says the above. Idol worshippers are apikorsom. You are bringing stories from Tanach to reach your own conclusion to disagree with the Chofetz Chaim? Or are you being misunderstood? Where in Shulchan Aruch does it say it is ever prohibited to condemn, mock or despise idol worshippers?
My point was that when speaking about Jews, one is playing with fire. Handle with care.
