Nations and organizations with known old pre-existing political/religious animosity towards Israel do not count as valid opinions on the matter.
I think we'd typically call that bias.
> And secondly, is your claim that every single one of these hundreds of large orgs are historically politically or religiously anti Israel?
Plenty of those organizations/countries do have historical problems when it comes to antisemitism which is obviously highly correlated with an anti-Israel bias. Which of these organizations/countries don't have a history of either blatant anti-Israel bias(i.e. clear double standards) and/or outright antisemitism?
