It's not just a character attack to point out that a glorified blog post pulled that number out of thin air.
It would be silly to ask someone to prove that a made up number is made up. How can I provide evidence for lack of evidence. A more reasonable starting point would be to bring up what evidence does exist for the 40k number and then evaluate that.
If you want to continue believing it, that's your prerogative. I don't have a dog in this fight. I'm just doing my part to counter misinformation from biased sources.
FWIW, the Human Rights Activists in Iran (Virginia-based NGO) puts the figure at 6,488
It is a character attack to call into question the validity of the source in general.
You did not provide evidence for your claim. You offered something else entirely. In the future it would be better to provide what is being requested instead of a distraction.
I don't have strong beliefs on this, I just wanted a conclusive source. You did not provide one.
You made the claim it's misinformation, support your claim (as you hold the burden of proof for your own claim given it's contrary to the status quo). You haven't tried that hard, you might as well give it a real shot.
You don't have to forget anything, just contextualize it. The United States already tried installing a puppet government in Iran and it went terribly. They were so unpopular that the CIA set up state-sponsored torture rings to quell dissent: https://en.wikipedia.org/wiki/SAVAK
Going back to the old way foments instability that jeopardizes the Gulf States, with precisely zero upsides to anyone that isn't a net oil exporter (namely, the US and Russia). If this was about protecting against genocide then the US would be invading Sudan and Gaza, not Iran. The death toll has nothing to do with how American leadership sees this conflict, and it has been like that for over half of a century.
