It's called moving the goalposts. You called out their Bs claim, so they just threw out another one.
Anyone can go and listen to npr up first. The title for yesterday includes "Israel escalates in Lebanon" and then today they point to Israel vowing repercussions for Iran. In the podcast itself, they talk about how this was almost certainly retaliation for the killing for the Hezbollah leader.
This whole idea that the whole of western media is ignoring what Israel is typical of the false Bs pushed by the op.
Your main claims were the all of the headlines "about how scary Iran is" (the fact that it was a headline about Israel escalating and Israel vowing repercussions) and "many of the stubs behind the Iran headlines made no mention of why they would fire missiles at Israel" (and the short story in NPR was about why they were retaliating). It directly contradicts it, using one of the most popular and prominent US news organizations.
Your original argument was that there were no headlines, which the other poster challenged. . .you then went not to say that the stories didn't give information about why they retaliated. It's absolutely a clear case of moving the goal posts.
Attempting to gaslighting me won't work, sorry. We've had too many interactions before for me not to be on the lookout for disingenuous positions.
