Nations and organizations with known old pre-existing political/religious animosity towards Israel do not count as valid opinions on the matter.

Don't we typically call that ad hominem? And secondly, is your claim that every single one of these hundreds of large orgs are historically politically or religiously anti Israel? I get that of course Iran is not a valid opinion, but all the rest? That stretches credulity.

I think we'd typically call that bias.

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?
