Looking for speakers and leaders on the movement to Free Palestine

I'm a therapist and I have clients with so much anxiety around what is happening in Palestine. I notice that when they engage with content or speakers that speak confidently about a Free Palestine. Especially ones that speak with love and inspiration, not anger and hate, my clients anxiety lessens. It helps them feel more ready to mobilize for this movement. They need some inspiration in the face of all this helplessness.

Can anyone recommend me some people who are leaders and speakers for this movement ? Kind of like what MLK Jr and Gandhi were for their respective oppressed people.
