Well, the thing is my entire experience from decades of being, you know, an Iranian. I used to be pretty religious (some might even remember me arguing in favor of Islam way back then on the forums). I was pretty into the whole religious government can work, and with voting and participating in the "process" things can get better.
I do have connections with both side (pro religion and anti religion) both family and otherwise. I have seen how the general sentiment has changed over the years. From what I have seen around me, and like comments and discussions on Persian speaking websites and boards, majority support Israel in their goal to destroy Hamas by any means. I don't mean everyone single person is this way, but from my experience (which is not a small sample), even in my rather large family which is pretty religious in general, pro-Israel is the majority.
The thing is, no offence, but you guys have no idea how deeply majority hate organizations like Hamas and Hezbollah. We have first hand experience of how awful it is to give these extreme nutjobs power and they wont let go no matter what.
Overall, all I have is my personal experience that is miles miles ahead of anyone else here. Added to that is my experience on both sides, where one day I was pretty fanatical about the regime side. I just did not wake up one day and randomly decide to be against everything I believed in for about 3 decades of my life. The pure (and sad in way) truth is that majority of Iranians are so sick and tired of living under extremist religious zealots that they do not care one bit about what happens in Gaza. To our eyes Hamas has to be destroyed no matter what, otherwise these things will never stop happening. They did try to give "power to the people" in 2006, and they turned around and voted to be governed under Hamas. With no more elections since that day, this is where we are now.
