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
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.
I don't think that Iran International did either, so calling their methodology into question is fair play.
