It's definitely bait but there is definitely not the same reaction to this among that group of people and when one asks the question "why?", there aren't a multitude if explanations that come to mind.

I guess that Iran felt like the strongest opponent to Israel, its history was not widely known by the protesters, and so it takes a little more to distance yourself.

There's maybe some disquiet in realizing that they're not someone you can side with, too.

And for sure some of the outlets followed by the protesters have ties to Iran, sadly.
