I have a less charitable and more direct answer. Right now there is a notion in Left that Israeli are the oppressor. In Iran large majority of population is Persian but MINO (Muslim in name only due to dictatorship). They are struggling to get freedom from the Islamic regime and getting some help from Israel. This flips the narrative in Left's mind (if they accept it) that Muslims can be oppressors too and that is untenable for them. especially because Left in Western nations has basically aligned themselves with muslims so its easier for them to just ignore it.

BTW its not just left here, I originally hail from India and you can feel the pin-drop silence from left on Iran there too. They just hope the rebellion gets crushed by regime like other ones and they'll pretend status quo.

My TLDR takeaway: Muslims only care about when they are oppressed & Left is completely aligned with them right now.
