I'm going to assume you're joking and this is a bit. But I'll answer anyway.
All leftists support Palestine against the colonizers who stole their homes and have been ethnically cleansing Palestinians for decades.
It's a basically almost a prerequisite to being a leftist and has been for decades. I have never heard of a leftist supporting an apartheid state like Israel. It would be like hearing a Conservative say they hate the troops.
They're just like us 🥰
