Palestinian PR groups and Hamas terrorists are left or right. But I do know that they target people on the left to recruit for protests because I've seen their websites. You can find the LW target groups on the USCPR website. (Lower left side of the home screen)
I also know that large, liberal church denominations are using the same terminology and slogans that the student protesters use. (Apartheid, false claims that Palestinians never had a chance for their own nation state, calling for the abolition of Israel as a nation) I have been involved locally with a few liberal churches in their community outreach and charity programs. I've attended their services and meetings. I've looked up the statements on Israeli-Palestinian issues on the websites of their national leadership. I dropped my jaw when I heard a Christ killer sermon used as inspiration for protests to stop today's Jews from killing. Never thought I'd hear a Christ killer sermon in the 21st century from the right or left.
Liberal denominations in the US are affiliated with a movement called Sabeel, which means "The Way" in Arabic. It was founded by a Palestinian Anglican priest, Rev. Naim Ateek, who has urged people to compare the Biblical sufferings of Jesus "caused byJews" to the sufferings of Palestinians "caused by Jews." According to Sabeel, any separate state for Palestinians must eventually lead to one nation in the region, with no Israel.
The denominations affiliated with Sabeel have churches and synods or dioceses in Palestine. They are promoting their own interests there.
The largest body of Presbyterians today is the PCUSA, a liberal denomination. They are strongly partnered with Sabeel. Here is a letter to the PCUSA from the ADL in 2022.

The PCUSA has also been criticized for meetings with Hezbollah.
The Anglican Church (Episcopal) supports Sabeel and its Anglican founder.
This Wikipedia article describes Sabeel in general as an ecumenical organization, but its section under Criticism indicates complaints of anti Semitism.
