The article as it is right now is sufficient for me. It reads:
>Opportunism
>On April 6, 2022, FRSO endorsed Brandon Johnson,[12] a Democrat who conflated anti-Zionism with antisemitism and supported Israel while denouncing Palestine.[13]
Maybe just add that Brandon was running as mayor of Chicago (from what I understand?). We could also make it clearer that like all Zionist politicians, Brandon understands anti-Zionism is not anti-Semitism, he just repeats Zionist propaganda to wilfully conflate the two (as the sentence reads right now, it implies he just made the mistake innocently once).
There's no reason to come out and say that FRSO is revisionist, in my opinion. At least not strictly over this. That endorsement stands well enough on its own that people can make their own takeaway from this, and choose to believe if FRSO is revisionist or not.
I realise that in other pages we have come out in support of one view or another but in regards to communist parties, we should be careful not to paint them with a broad brush.
