I'm not well informed either, but every Western media outlet has suddenly decided to condemn Raeisi as "the executioner of the regime", "the butcher of Tehran" etc. Meanwhile, they've started pushing the narrative that in the upcoming elections to replace him, the current regime will collapse and "democratic forces" will prevail, because of the protests that were going on a while ago.

This tells me three things:

a) Raeisi might or might not have been a decent guy, but he was most likely quite popular.

b) The current Iranian government will come out of this crisis just fine.

c) The West will be trying to incite another color revolution in Iran in the coming weeks/months.
